Landlord (April 2017)


Gabby and Nina deliver what other agency’s only promise. Their customer service is above and beyond expectations.


Landlord (March 2017)


Communication is always friendly, professional and reliable. I was pleasantly surprised and grateful when Gabby swept our balcony before an open for inspection. 


Landlord (March 2017)


Gabby is the most professional real estate agent I have worked with. She has made my experience with Castran Gilbert such a delight. She is very responsive, courteous and was able to find me a tenant within such a short timeframe

Some years ago I had a very negative experience with Castran and Gilbert. I was very cautious in returning to Castran and Gilbert however after some discussion with my building manager I was assured Gabby was a professional and dedicated agent and not like the previous agent who managed my rental property. I have to say  I have all the confidence in the world now with Castran and Gilbert and this is as a direct result of my dealings with Gabby. I sincerely hope she remains in that role as I believe she brings integrity and a level of professionalism that stands out from other agents.

Tenant- Blythswood Court, Kew (February 2017)


Rental experience: We are downsizers who have sold our family home and were cautiously seeking a rental property – what horrors would we experience?!? We were blown away by the customer service and professionalism of Gabby Mercuri and the whole Property Management team at Castran Gilbert. Professional yet friendly, thorough yet relaxed. Gabby is amazing in her energy and responsiveness, with extraordinary attention to every detail. The requirements of the landlord have been communicated openly and clearly, and she has responded to all our queries rapidly and thoroughly. It is evident that CG represent the interests of the landlord and at the same time respect those of the tenant, achieving a rare win-win outcome. A huge round of applause to Gabby, and thanks to CG’s Property Management team: outstanding.

Tenant - River Street, South Yarra (December 2016)

I have rented an apartment through Castran Gilbert for the past 3.5 years. I was approved for the apartment on the day I applied and have had the same efficient service whenever I have been in touch with them. The agents have been courteous and helpful whenever I have needed to get in touch. I would recommend this estate agency to anyone looking for a property in Melbourne.


Tenant - River Street, South Yarra (December 2016)

I have really enjoyed living in the apartment and have appreciated all your help over the last 3 and a half years. I will definitely recommend Castran Gilbert to friends in the future.


Tenant - River Street, South Yarra (November 2016)

I rented an apartment in 77 River St. I would reccomend Castran and Gilbert as a tenant or an owner leasing a property. All small maintenance issues fixed promptly and communication with Gabby and Nina fantastic.

It has been a pleasant and great tenancy experience with Gabby and Nina at CastranGilbert for the last three years. Both of them are very efficient and helpful!


Tenant - Dandenong Road, Caulfield North (October 2016)

As a tenant I had wonderful property managers (Gabby and Nina). Very attentive and always back in contact with me as quickly as possible. They were always there to help when needed and they added to a wonderful renting experience.


Tenant - Williams Road, South Yarra (September 2016)

 A very professional real estate agent. Came when they said they would, fixed things promptly. Communication was painless and effective throughout my tenancy. Their real estate agents were very friendly and never treated me like a second class citizen just because I was renting. The whole process from picking up to returning the keys was painless and simple. Thoroughly enjoyed my tenancy and couldn’t recommend them highly enough!


Tenant - Williams Road, South Yarra (July 2016)

Thank you again, you have been one of the most helpful and considerate agents I have ever had.


Tenant - Riversdale Road, Hawthorn (June 2016)

I really wish I had a way to extend our stay at the current place and I can only hope and pray that the next agent is as good and supportive as you’ve always been; and regardless, we’d definitely miss Camberwell and you. Thank you for everything, really.


Landlord - Rose Lane, Melbourne (June 2016)

Thanks again for managing my place so properly.


Tenant - Queens Avenue, Hawthorn (June 2016)

Finally I would like to thank you for everything from great services and other things you have provided us with here in this apartment, and I’m so sorry if there is anything that might go wrong between us.


Tenant - River Street, South Yarra (June 2016)

I have never had such efficient service leasing a property! I work in Real Estate myself and know how busy the property management team is so we were very impressed!


Landlord - High Street, Prahran (May 2016)

If I ever have an investment property to rent i would certainly have you as my agent :) You are very professional and have looked after mine and owners interests.

Tenant - Sutherland Road, Armadale (February 2016)

I have worked with Gabby to secure my rental and she has been very helpful. She has promptly returned my calls and emails, even when I have had issues with gas connection and water at the apartment. With the property address not allowing pets she offered to help me find another that would be more suitable.


Landlord - River Street, South Yarra (February 2016)

Thank you very much for your great and very professional work so far. You are a property manager that everyone would desire and I will warmly recommend you to anybody who mentions need to lease their place.  If we decide to lease it again (if we find it too small for living) I will certainly contact you.


Landlord - River Street, South Yarra

Gabby, you cannot imagine how much I appreciate your work. Thank you so much.


Tenant - River Street, South Yarra

To be honest Gabrielle, I am so much more than happy, I am blown away.

Sadly I have had really negative experiences with Property Managers whilst living in Melbourne the past few years, and since day one with Castran Gilbert it has been great.

Responsive, helpful, polite, friendly, well informed and diligent – just excellent.

I am so glad yourself and Castran Gilbert are going against what seems to be the trend.


Tenant - River Street, South Yarra

Thank you for being so responsive and pleasant to communicate with, it’s such a lovely change to what I’m used to dealing with.


Landlord - Williams Road, South Yarra

I would like to take this opportunity to sincerely thank you for your amazing efforts with this property. The time in which you managed to lease it out was nothing short of brilliant – 5 days – I am over the moon!

Once again you have proved to be the best in the industry. If anyone asks me if I know of a good agent I will be sure to point them your way.

I am so happy with all your efforts and am truly delighted that you have leased the property in such a short time frame.


Landlord - River Street, South Yarra

I will certainly recommend you if I hear that somebody needs a good property manager.


Landlord - Merton Street, Albert Park

Very grateful for your prompt and professional help.


Tenant - River Street, South Yarra

Thanks Gabby, I’d like to thank you for making everything so simple. Greatly appreciated.
