Pricy, but the location and the amenities are worth it - how many other budget hotels in Tokyo have a rooftop onsen?
Rooms are bigger than average, with a walk- in shower in the bathroom, rather than a shower-over-bath. Only mark-down is the weak WiFi signal in the rooms. The proximity to the train line means lots of train rattle if you leave the window open, but it's worth it for the short walk to three train stations - Suehirocho, Okachimachi, and Akihabara.
That rooftop onsen is small, but fully-equipped with a sauna, cold bath, and indoor and outdoor hot baths. Brilliant for recovery after a long day of exploring on foot.
