The place is in a nice quiet neighbourhood, and was very clean! The owners were responsive and reply fairly quickly to any questions you might have.
The place is a bit tight for two; however, the owners did warn us of this, and there was actually a surprising amount of space to put our luggages. They have a lot of amenities, like cream, benedryl, detergent, etc, and the owner also goes through how to separate your rubbish on the first day. The place is airconditioned, has a small fridge, sink and stove.
It is about 10-15 minute walk to the train station, which is then approximately 40 minutes to Shinjuku station and 50 to Tokyo station. There's a 7-11 about 10 minutes walk away, and a coin laundry on the other side of the station if you need it.
There are quite a few restaurant around the area as well; while I didn't get the chance to try all of them, the once I did go to were great. Keep in mind, however, it seems that most don't speak English, so learning a few sentences of basic Japanese (or bringing a translator) would be advised.
It was a really nice place and we very much enjoyed the stay!
