Excellent location (they're right by a Metro entrance, JR is a bit more of a walk), clearly marked signs outdoors. Clean + private living space. The staff was very friendly and accommodating for check-in, and they'll hold your bags after check-out if needed (check-in/out can all be done by yourself as well)
Only con is walls are thin so you can hear if other guests are noisy, but didn't have any trouble with outside noise
