We had a very pleasant stay at Stephanie and Tom's apartment. The flat is very nice, beautifully decorated and well located. You can either choose the tube or the bus to reach the center, and the 88 bus drives all night for party animals.
The apartment has all facilities, we could also cook there and Stephanie was available to help us with any question. She even set up a small bed in the small bedroom so my friend who was quite ill could cough all the night without waking me up ;-) We will surely come back there, during the summer to enjoy the nice little garden;
