John and his family are great and very flexible hosts. The flat and how to start the heating,... was shown and explained to us in person. The flat is great for up to four people (would even sleep a fifth person in the common room) with great access to London's tourist hot spots (about 20 min by bus to Leicester Square with a bus stop right in front of the house). The street is quite busy, so especially in the two bedrooms it is quite noisy during the night. A big supermarket is located directly at a bus stop on the way from town, another smaller one next door.
