We really enjoyed our stay at Alex's place. It was spacious, comfortable, and had everything we needed for a wonderful experience in London including a washing machine, iron, etc. It isn't in the heart of the city, but it is easily accessible by Tube and there are some excellent options around for those who don't wish to travel late at night (the Union Tavern, etc.). Can't recommend the apartment more, the price is great and I promise you will enjoy your stay.
