I was pretty disappointed in this Airbnb. There were some basic issues with cleanliness-- the entire ground floor of the building smells strongly of some kind of urine or animal odor, so as a result, I couldn't open any windows or get any fresh air in the apartment. The sheets had clearly not been changed between the previous guest and me, because I discovered little black hairs all over the bedding when I went to bed. The hosts did remedy this when notified, but because I arrived so late, I still ended up staying a night in a dirty bed. As other reviews have mentioned, the bathroom is not very well designed, and as a result, water covers the floor of the bathroom and seeps down into the living area anytime one tries to take a shower. The internet was quite spotty, frequently requiring that I restart the router to get a reasonable signal. Other than these issues, the apartment was basic but functional and quite nice. Naoki was fairly responsive and handled issues as they came up, so my overall experience was okay, but given the price-- there are definitely better quality Airbnbs that are more affordable in Tokyo. Also, I would only recommend it for a solo traveler given the size of the bed and that there's no actual door between the toilet and the bedroom.
