We really enjoyed our stay at the apartment in SOHO, London. An almost perfect location, just walk out the door and you're in the middle of bars, restaurants, shops and people milling around. The apartment was nice, it felt private, comfortable and surprisingly quiet. I love that the lounge was on the corner of the building, with views down onto the street.
My only complaint, which to be honest just confuses me, is why you'd have such a nice place, in such a great location and have the entrance / foyer look and smell so bad. The carpet in the common area heading up the stairs was nasty. Surely you could replace that carpet for a few hundred pounds ? There were dirty tissues and chocolate bar wrappers lying around as well. One of the reasons we stayed there was to impress some friends before dinner ... we couldn't invite them over because it was so awful.
Other than that, we liked it, and loved London.
