This is quite possibly one of the best AirBnb's I've had the pleasure to stay in. The location is excellent, the space is fantastic, it's perfectly appointed with a great kitchen, living room and bedroom. The washing machine (with dryer!) is a godsend for the long term traveler.
The upright piano is so relaxing for a musician who doesn't get enough time to ever play.
Also, and this is important; the shower is easy to use, well pressured and properly hot.
It will be the first place I check availability on whenever I come to London.
