Pros: convenient area for self stay and access to the best places to visit in Tokyo, good size place, host was very friendly and polite. Bathroom and toilet clean, kitchen has all you need for self catering, WiFi is good.
Cons: was quite dirty when we arrived unfortunately (blood on one of the duvets and the walls, mold on curtains to name the worst bits), one beds mattress was broken and unsleepable, the trains are a bit too noisy and wake you up in the morning and if you sleep before 1am.
Overall if the cleaning service improves and you are going out as a tourist in Tokyo (out early and in late) this is a good place to stay.
