Location: It's NOT close to Ueno station. The title is bit misleading in someway. We took the Keisei skyliner from airport to the Ueno station and walked 20 mins. Yes there's is another station nearby within 5 mins but you probably will never use. The Station we go most often is Uguisudani which is around 10 mins away.
Room: It's a bit small but has everything inside.
Amenities: There's 7 11, cafe , restaurant within 100m. You don't need to worry about breakfast.
Overall: it's good but you need to expect a bit of walking.
