Overall, a pleasant stay! The staff may not always be at the counter, but the instruction to check-in and check-out are quite clear, and comfybed is quite responsive through Airbnb chat. It's the quite a cheap option for last minute stay booking and who wants a centre place, it's about 10 mins walk to Ginza, 18mins walk to Tokyo station, many convenient shops nearby. The neighbourhood is quite quiet at night.
The room is quite efficient, good for one person or couple stay with small luggage. Although you may hear a bit noise if there's people at the corridor, but it's quite quiet at night in the room, you won't hear people stay next to you.
