We had a fantastic stay at Ruth's flat. The flat itself is beautifully decorated and equipped with everything you might need. It's on a quiet street but is literally 5 mins walk from the tube and there are Waitrose and Sainsburys supermarkets very close by. Hampstead Heath is about a 20 min walk away and has a fantastic play park for kids, as well as lots of nice places to eat or have a beer in Hampstead village. Ruth was a great host and gave us all the information we needed. We really appreciated the supplies left in the fridge and also her DVD collection! I'd highly recommend this as a place to stay in London.
