Surprisingly there are a lot of negative reviews on here, perhaps I\'m a one off example but I had a good experience with Citi Quays(!)
I was only with this estate agent for 6-7 months - my tenancy ending when the landlord sold the house in the run up to the Olympics. Citi Quays gave me 10weeks notice so that I could find somewhere, which is more than they needed to and it left me with plenty of time to find somewhere else.
Pros - Very easy to deal with. Not money grabbing. 0 issues getting my deposit back. Repaired any issues during tennancy. I locked myself outside accidentily once and they sent someone no troubles.
Cons - Sometimes need to mention something a few times to get it done but that\'s the only thing I can think of.
