We have stayed at Suda’s place several times before as it is very convenient for visiting my son. The location, very close to Tamagawagakuenmae Station is convenient for visiting central Tokyo, Kamakura and Yokohama, although you always need to be prepared for hour long train journeys, as with most places in Tokyo - the area is so huge compared to most European cities.
The accommodation is perfect for one person. It is cramped for two but we make it work, you just have to be organised with putting bedding away. Storage in the apartment is good, which helps and it’s great to have a washing machine and to be able to hang washing outside.
Suda is a helpful and responsive host, he responds quickly to all requests.
Tamagawagakuenmae is a nice place to stay with a couple of good supermarkets and a variety of eating out options. We particularly recommend the fish izakaya opposite the station.
