All - I would like to highly recommend Paramount agency and James Carter in particular. James quickly understood my requirements and arranged viewings only of properties meeting my criteria. But best of all, he got me to my present flat in West Hampstead; I have called several times to other agencies that managed this property but was only James the one that quickly returned my calls and arranged everything for me be leaving here. The agency even helped the landlord and us to closed the agreement by resigning to part of their commission.
Do not hesitate to contact James at Paramount if you are moving to WH.
