My wife and I had a wonderfull time at AJ's house!
The place is very well located and it is extremely clean. The bed is exceptionnaly good, if you have back problem, it is the place to stay!
At first sight we were a bite surprised because we did not understand when we booked on airbnb that it was one room in a shared appartment (with AJ). However he is a very nice guy and discret as a ninja. He gave us usefull advice and we had the best time in London!!
