I lived at toshi's house for 4 nights. His house is in such a nice area with down town atomosphare, very enjoyable for taking a walk around the area. also easy to access from Ueno by bus or you can walk from some metro or train stations easily. Toshi san is such a great host who can explain everything I needed and I felt at home in his house. I definately come back again to have more time there next time.
