I really liked staying at the Guest House, it had everything I needed for the stay and they were so helpful and easy to communicate with. Also staying in Tsukiji was great because it's away from the busier areas but close enough to take the subway to any destination you want. Also the Denny's across the bridge is open 24 hours and some sushi places in the market are also open 24 hours. Family Mart and 7/11 are also right down the street. If I come back to Tokyo, I will 100% stay here again.
