Excellent value. Easy walk to 2 different tube stations which gets you to all London sites quickly. Close enough to the sites but in a quiet little suburb with a nice selection of restaurants and parks.
The host was wonderful and helped at all times. Since we were arriving on Christmas day when everything was closed we were worried about getting food on the morning of arrival. Our host was nice enough at our request to buy some cereal and milk and had it waiting for us so we knew we had something to eat when we arrived. Although we didn't use it, our host also allowed us to use her printer when someone in our group initially thought she needed a paper for school. Extremely nice and thoughtful host!
