I recently moved into a flat in Tower Hill and dealt with Jamie in the city office.
The process was smooth throughout even though there were times when I had to wait a little longer than expected for a return email. Having said this, I was always kept updated and in the loop when necessary over 2 months.
The flat was clean and tidy when I moved in, one of the blinds was a little lose, but Jamie was very helpful in getting small issues resolved, such as fobs and what not.
Would recommend, pleasure to deal with.
