We're extremely happy with the stay for our family of 4. The unit is small, as expected in Tokyo, but we're very comfortable. The best part is the location, where we can see Sensoji and the SkyTree from our windows. Minutes walk to Sensoji and the amazing surrounding area with so much shopping and food. We visited over New Year, and got to see so many local people visit the temple in traditional clothing, plus the tens of food stalls temporarily on the Sensoji grounds, and hundreds if not thousands of people waiting in line to visit the temple for their New Year traditions. Very convenient 10 minute walk from the Asakusa subway station that took us everywhere. Also 7-Eleven, so many restaurants and shopping, banks made the visit very easy.
The beds were comfortable but being very low directly on the ground was difficult for my elderly mother to get up from. Kitchen and bathroom were clean. Coin-operated washer and dryer were convenient. Highly recommended.
