Our stay at this place was a big highlight of our recent Japan trip. Definitely high up among the best Airbnb experiences we had so far. After a bunch of nights in regular Japanese hotels (which can be a bit 'sterile' after a while with their small uniform bathrooms and tiny beds...) we arrived at this old house. And then the host showed us around in his neighborhood and introduced us to a few of the merchants and shop owners, and we immediately felt at home. The place is absolutely charming and pretty original, but also has modern amenities. The AC unit is able to cool the sleeping area to a comfortable temperature even at a hot day. The kitchen is well-stocked and has a two-burner stove. We had great meals at the house by simply buying dishes from the local vendors on the nearby shopping street.
While it takes about 15 min to walk to one of the train stations there are several buses that make it easy to connect with train lines without the need for much walking. Both Apple and Google Maps had reliable information on the buses and it was no problem to use them (keep in mind that buses run on the left side when you study the timetables posted at a busstop trying to go in a certain direction...;-). While for us the small neighborhood around the house was a main attraction, there is also a major Tokyo tourist destination in 20 min walking distance: The SkyTree skyscraper and shopping center is worthwhile visiting. The view from the top is magnificent (try to do it on a clear day). Another nice thing to do is simply to walk to the rivers and enjoy the parks that were created along their banks. Especially nice is Sumida Park along a small creek southeast of the SkyTree.
Bottom line: If you are looking for a special Japan experience a bit away from the standard tourist attractions this is the place to rent! Go for it!
