This experience truly made me a believer in AirBnb. Sayoko has a wonderful flat that is very reasonable considering the limited space in Tokyo. The area is also wonderful - definitely a local feel to it, we stayed while the local Matsuri festival was going on, and were able to enjoy some nice festival food. It is also very accessible to downtown Tokyo from the Osaki station. I would definitely recommend touring the street (from the door turn left and keep walking for 10-15 minutes) to see the number of local restaurants and shops it has. Of course the best part is Sayoko herself - she was a very, very gracious host, provided amenities and snacks for us, very accessible by e-mail/phone, and she also has a folder with a lot of recommended restaurants around the area. Would stay there if we visited Tokyo again.
