We really enjoyed our stay. The photos were accurate, so we were prepared for the narrow stairs and 3 toilets/one shower - I will miss Japanese bathrooms, so good!
We had four single western beds on the top floor (2 semi-private curtained rooms either side of the stairs/toilet, and the bottom floor room, which was a sofa bed & a tatami mat futon. We all slept well, though the exit sign lights were bright.
The closest train station (Ikejiri-ōhashi Station) is on a private (non-Tokyo metro) line, fine for travelling with Suica/Pasmo/Icoca cards, but change at Shibya if you're on a 24/48/72 hour metro pass or buy a ticket when you arrive at the station.
The local supermarkets are well marked on a map provided our hosts and we ate well, cooking & re-heating, it's a big fridge/freezer/microwave/stove with a mix of Japanese & western utensils (we supplemented the utensils provided with our own chopsticks).
We were fortunate indeed that it was peak Sakura (early this year), the canal and walk from Naka-meguru station was stunning.
Our family of six (8 & 10yr boys, us and grandparents) would happily stay again & gladly recommend Yukari&Davi's place.
