Home was as advertised. Great location: close to food, shopping and transit. As mentioned in the ad, understand that this is definitely an old building and that should factor into your expectations.
The home was clean and spacious enough for a family of five. We really liked that there was a toilet and sink upstairs as well as the ones downstairs. The stairs were also wider and not quite as steep as in other places in Japan that we stayed. This was important as we were traveling with some family members who were somewhat mobility impaired. There was a table and seating enough for all five of us to eat together and plan our day. Kitchen was equipped and we did use it to cook some light meals. The bath had a lingering odor (as seems to be due course for older homes in Japan) and was manageable with ventilation but a stronger fan would have been appreciated.
Although the fan in the bathroom was not strong enough, the AC units throughout the home and the ventilation fans in the kitchen and upstairs sink were plenty strong. The hosts were helpful and promptly responded to requests. They also proactively followed up before, during and after our stay. All in all, a great value close to everything in Shinjuku.
