Great place to stay outside of super-central Tokyo. A small supermarket is right next to the place, the "main" street is not too far off and has a lot of chain restaurants or convenience stores. There is a nice park about 15-20 minutes on foot from the Airbnb and you can see Kawazu cherries in early March. Mid March has the somei yoshino cherry trees lining a small promenade along the riverbed!
As to the place itself - it's great for either a solo traveller with a big suitcase or two people who are perhaps backpacking. Two large suitcases will not fit easily at all but for me as a solo traveller, it was spacious enough. The internet is fantastic - both fast and stable, which is rare in Airbnbs - and overall it feels more like a small hotel room than an Airbnb.
