We greatly enjoyed staying at Jon's place. It was conveniently located in a nice neighborhood close to Waterloo station, the London Eye and plenty of great restaurants. The bakery around the corner was a nice bonus for morning coffee and snacks.
The apartment was clean and bright and had plenty of room for our group. The upstairs bedrooms got a little hot in the summer so we appreciated the fans that were already in the rooms.
I would certainly stay here again and recommend it to others.
