Traffic: Much closer to Ikebukuro than I originally thought. About 10 minutes by train to Oyama station and 10-15 minutes walk. Another choice is by metro, it is also not far away from metro station.
Room: Clean and comfortable. Host will ask to follow reasonable rulers. This is totally good and acceptable because in other to keep the comfortable environment. Especially important when sharing the house with other guests.
Store: One Lawson convenient store is in front of house. A lot of restaurants on the road to Oyama station. One bargain supermarket is very close and open 24h. A coin clothes washing store is nearby.
Hospitality: Host shared places for enjoying Sakura bloom. One of the place is not far away from the house. Do not forget to ask his recommendation if you go during Sakura season. He also helps when I have questions.
