Had a lovely four nights in Peter's flat, would definitely stay there again. We arrived a little early and the cleaning lady was still doing her thing, so we checked in with Nick the doorman and sat in the Vietnamese cafe next door and had a little snack and some coffee. Nick came and got us when the flat was ready, which was great.
Two bedrooms and two bathrooms was perfect since we were two couples sharing. Plenty of space, nicely furnished and decorated, very clean and modern. We were worried we would hear the train outside, but heard nothing! Our only quibbles were - it was really warm in London, and in the apartment (we are used to heavy air conditioning), and the mattresses were not our favorite - but after a full day out walking about we still slept fine. We had some comical moments with the washing machine trying to figure out how to work it, but survived.
Quit area, but Tate Modern, plenty of pubs, restaurants, and a few Tesco Expresses less then five minutes away. Really convenient.
Overall nice space, good location directly between two tube stations, which makes all the difference. Would definitely stay again! Highly recommended!
