Naoki’s apartment is really conveniently located, very close to the exciting Waseda neighborhood near major JR and Tokyo Metro stations. I enjoyed staying on the river and it was a nice walk to/from the stations. Convenient stores are easily accessible, about a 2-3 minute walk away! Although it could be tough to find the apartment, Naoki has a detailed guide making it easy to find. Overall a good option for a solo traveler.
