Kenny and Zach's place is really great! They are both extremely friendly and welcoming and made us feel right at home. They also have some really great suggestions for things to do, museums, exhibits, places to eat, transportation, etc. Their house and the room was great, clean, etc. You can walk to a lot of great places right from their house... there is some great restaurants and Wine Bars very close by. If you like science I would highly recommend seeing the British Museum of Science (this was one of Zach's recommendations), I think we spent 3-4 hours there on a rainy day. Overall highly recommended, we had a great time!
