We stayed there for a month. It was bearable enough even with two people but I wouldn't recommend it with more than that.
It was very clean when we arrived and the host was very responsive and gave us everything we needed when asked.
Walls are very thin so be ready to hear everything around you ( mostly at night )
First floor so even if it is clean there's a lot of cockroaches around, but it's not the fault of the host.
It's very dark in there so I was missing some sunlights.
Very near conbinis and stores as well as the temple of Asakusa at a 2min walk.
Overall i'd give a good 7/10 for the price !
Thank you :)
