Fukudaya offers the ryokan experience, with futon bedding on tatami (woven reed mats); some rooms have private bathrooms (single/double from ¥9000/12,000), but there is also a communal o-furo (Japanese-style bath). Western-style rooms are cheaper, but not as nice. Shinsen station is closer, but it's easier to find coming from Shibuya and also easier to catch a cab (around ¥1000). Curfew is 11.30pm.
