This was a wonderful place to stay! It was very clean and felt very safe. There are a total of four beds though they are all in the same room. And there is luggage storage lockers for before and after check in/check out if needed.
There is also quite a lot to do around the area (coffee shops, restaurants, bars) and public transportation is only about an 8 minute walk. The location is set back down a street that does get pretty dark at night, which was a little unnerving at first, but once you get used to it, it feels very safe. I would definitely recommend staying here and will stay again if I am ever back in Tokyo.
