Koji and Nami's place is highly recommended even for solo travelers. It is walking distance to Tateishi station and the neighborhood is quiet, safe and clean. The lodge itself is very clean and comfortable to stay in. There are laminated instructions pinned on the walls which made life easier for me. Koji and Nami are a cute and fun couple :) Too cool and helpful which made my stay in Tokyo a memorable one. I would definitely stay here again given the chance to go back to Japan.
