House was very comfortable, clean, and you would feel at home. The area is a walk from the JR Ueno station but have other subways closer to the area. We would walk to Ueno station everyday and it was a nice walk. However with luggages you might want to take the closer stations.
It is very helpful as well that there is elevator. Also very convenient to have a lot of space for outside and inside to hang clothes to dry. The house itself is very spacious for a Japanese house. It has a hint of west and east feel to the house. Three bedrooms plus the living room were plenty of space for our group.
YK was very helpful and accommodating and very quick to reply.
If you want to stay at Ueno Tokyo, I would recommend this house and the area. You feel slight suburb feels just before hitting the JR Ueno area.
