Our stay at Chieko's place was great. She was very thoughtful and welcoming and her place was great to stay at. It was close to two metro stations in a relatively quiet neighborhood. It took about half an hour to get to Shibuya, making it a great location for people wanting to be close to the center, yet stay away from the extremely busy parts of Tokyo.
The place itself is very clean and relatively spacious for two, so no complaints there. The heating worked well, which was very important considering we went at the end of December.
