The apartment was very nice. Clean, quite big. Separate toilette. Very nice shower. The interior is very nice. Check-in and out went very smootly and communication with host was very easy. It's very well situated when you are going to Narita airport since you can walk to the station and catch the train there. Very convenient. Coffee, tea and washing powder is provided, I think that is great. The area is very quite even though you are close to everything. We have stayed in Oshiage before and we like it.
Only draw back was that our apartment was on ground floor so the window was "covered with white" so we could not look out or get the sun in. This was not mentioned before hand. I asked to change apartment but this could not be done. This is though a matter of "taste". I recommend the house and the apartments.
