My wife and I, together with a couple of friends, stayed in this beautiful flat for three nights for vacation. We have really appreciated our stay: the flat is located in a very nice neighborhood, it's clean, quiet, well equipped and very close to the tube: it takes ten minutes walking to Westminster Bridge or the same time to get to Piccadilly Circus taking the underground. Oh, and if you look out of the window, you can see The Shard!
Catalina has answered all our questions quickly and she has provided us some tips to get there easily: she's a kind and attentive host indeed.
Everything went smoothly, so we certainly recommend this accommodation!
