A nice, chill capsule hotel / hostel. Beds were pretty standard and comfortable and it was quiet at night for sleeping (no noise allowed after midnight). Most guests are Japanese and it's fun to hang out with them in the common room and have a beer at the end of the day. Staff are also very nice, especially Ayumi!
Location is walkable to Kochi station but it's a bit far from Hirome and Kochi castle, so you have to take a 20-30 minute bus. They also have a limited number of parking spots so if you're driving, I would advise booking early to reserve a spot, otherwise you have to go find paid parking.
Most staff don't speak a lot of English so you may have to use Japanese.
