Yuka’s place is big for Japanese standards. It has plenty of space for large groups. The first floor seems like an old shop converted into a dining area. There is no sitting area (living room), which is not unusual for most Japanese places in big cities. The place is clean. The hot water for the shower was great.
The staircase to the second floor is narrow, we decided to leave all our luggage on the first floor so we don’t damage anything. The room with the two beds is facing the street; therefore, you will be able to hear cars and buses in the early morning, bring ear plugs if you are a light sleeper.
Overall, we would love to stay again in the future if we come back to Tokyo. They are just a 5 minute walk from a JR station.
