This place was nothing short of amazing. Extremely (!!!) clean room, responsible and responsive host, clear check-in instructions, great English guide for using room amenities, spacious for 2 luggages, fully-equipped kitchen (pots and pans, cutlery, and even oil/salt/pepper) and Netflix. The location was easily accessible from Nakano station (unsheltered, only inconvenient for rainy days) and the neighbourhood can be quite quiet. The place is surrounded by many local eateries. Cons might be the toiletbowl not having a spray/biget or that the bathroom sink/shower cubicle might be too small for taller people. Most importantly, Aileen was sweet and responsive to our needs and helped us out promptly. The stay here was definitely comparable to a hotel stay! Thank you Aileen :)
