Our stay at Ben's place has been very nice. Everything is as it is described. The place is very well equipped with a microwave, an iron, a coffee machine, a fridge, etc. The room was a bit small but we already knew that from the comments and we found it comfortable. The heating was on so it was a very warm place to relax yourself after having seen London all day.
The subway station Swiss Cottage is very close, just ten minutes walking and it connects you to the city center in about 20 minutes. I would totally recommend this place.
