Great place, I stayed there for 20 days with a friend. It is realy well located. You have 2 different konbini (24h open) within a radius of 200m, and a market just next to the building. It's 5min from the Oshiage metro station, and the Skytree shopping center. The flat is better for 2 or 3 people, but we had 2 additional guests during the first weekend (thus 4 peoples) and I can tell it's still good. I definitely recommand the place.
