Had just relocated to London and on my first day of flat hunting I rang a handful of agents - after looking at some rental flats on Rightmove. Spoke to James Mitchell at the Canary Wharf office, and after advising the flat I called about was already gone - he suggested another just on the market at Nth Greenwich. Arranged a viewing the same afternoon - and I put in an offer after seeing it.
James was straightforward to deal with and kept me updated during the process - which took 7 working days from viewing to signing contracts. Any queries I had were dealt with and I would recommend the agency.
