what we liked:
cleanliness, friendly staff who is responsive to emails (the only way to contact them if you need exchange your towels for new ones) although they're not on site, working AC in good condition, in quiet neighborhood although 17min from Asakusa station, close to SkyTree tower, plenty of room, lobby with kitchenet with microwave, toaster, waterboiler, utensils, plates, and laundry (we didnt use this; cant comment on its condition), we utilized the dining tables few nights which were very helpful.
what we didn't like: bit walking to stations but doable unless you're with small children, breakfast is just some thick slices of breads with butter and sugar - if this information was available prior to booking our stay, we'd have stayed else where because we were looking for a place with descent breakfast not some slices of bread with instant coffees. they didn't clean rooms and or changed bed sheets even though we stayed 4 nights. i wish this information were available on hotels.com
