Beware: we got lost because the address in English was not correct in Goggle maps. Use the Japanese one for the correct location!
Otherwise great location for travelers. Near Okubo station (5 min) and walking distance to Shin-Okubo (10 min) which are well connected to major subway lines to Shinjuku, Shibuya, and Ikebukuro. The surrounding area seems to have a large international community of Vietnamese, Korean, and other ethnicities, which is a bit different from the usual Tokyo experience. I really enjoyed seeing a different side of Tokyo and exploring the area. The room is a bit small for two people, but we made it work for the few days we were there!
