Such a lovely team that work at Costello, they are eager to help, proactive and do it all with kindness. It is very clear that Costello has the best interest for both landlords and tenants in mind and works hard to create a relationship that both sides benefit from. They act in a timely manner to get the job done but also taking their time to make sure that the tenant is perfectly placed and matched into a house that they can make a home. Could not recommend them more!

Thanks Sergio for 5* service recently regarding a property we are thinking of letting. His knowledge, personal attention and professionalism were a breath of fresh air. At last! an agent who offers factual, expert advice, and what we needed to hear instead of what he thought we wanted to hear. If we proceed to let i will certainly only use these guys.

On behalf of the Spetisbury Festival Committee, I would like to express our sincere gratitude for your sponsorship of Spetisbury Country Day, the boards you managed to get out helped tremendously in advertising the day and all done with very little notice is testament to your company's organisation skills.

We are renting a flat through Costello and we are very pleased with the way it's been managed. Recently our boiler broke down and in matter of hours they have sent an engineer to sort the problem. Children came back to school to a warm house. Very very pleased with Sergio and the team. They were prompt and professional! Gabby Wilson
