The house isn't sound proof, normal talking volume can b heard by people next door, the stairs to the too is very narrow and steep, you have to be very careful walking up, has 2 bath rooms and 2 toilets. Everything else is about average. It says on google around 10 walk from Okachimachi station to the place, but it's actually a lot longer than that. If you have a lot luggage, I recommend you taking the taxi.
