I believe we are now closed. Thank you for all your help. We are very happy with your wonderful management of the whole process. It has been a pleasure for us to deal with yourself and the professionalism of the whole service was really impressive.

Many many thanks Catherine for the beautiful house warming gift. It’s so thoughtful of you and very much appreciated. 

We’re really so happy to have finally moved in and it feels great! We love the apartment and already feel at home even midst all the chaos of boxes! It was  a marathon day yesterday and recovering very slowly today!! 

Thank you Catherine also for all your support and advice over the last few months…you’ve been great and an absolute pleasure to deal with. We felt you were  with us all the way! 

Drop in any evening you’re around…we’d love to see you and have a glass of wine together!

I just wanted to say thank you so much for all your support over the last few months. I had no idea how stressful the process is!  The house was in immaculate condition and she had  left a lovely note and bottle of prosecco in the fridge.

It was so thoughtful and greatly appreciated.

Lovely to know the house has gone to decent, honourable people who will enjoy it.  I hope you’re having a glass of wine this evening to celebrate your tenacity & ability in getting the house over the line.  Not sure many estate agents would have given it the care, attention & professionalism that was necessary for a successful outcome…well done.  

Thank you for all your assistance. It was an absolute pleasure dealing with you.
