Jian's spot was a great find, and we would book again when returning to Tokyo!
It's tucked into a quieter neighborhood about 25-30 mins from the central parts of the city, but very close to Asukusa (fun area to visit) and conveniently located just a few blocks walk from a subway station, so it's really easy to get around. (Also, for anyone who is directionally challenged like myself, it's super helpful that the building has a bright glowing green sign outside so it's easy to spot every time.)
Everything was very clean, and the bathroom included a small tub which was nice to use after long days out roaming. The room is as pictured, a little on the smaller side, so it's not somewhere you'd necessarily want to hang around for a lazy day, but perfect if you plan to be out and about most of the time and then back for a good rest. We stayed for 4 nights and were comfortable/happy with this choice, highly recommend!
