Our stay at Masaki & Haruko's was fantastic. It was the most spacious and comfortable place we stayed in on our trip.
It's located about 5 mins walk from Tabata station, that's on a major JR line. It is in a family friendly, more residential type area. So if you're looking to be in the hustle-bustle of a Shibuya-type area, this may not be for you. We, however, found it convenient enough to get back to and a nice quiet place to return to.
You do, however, have to walk up a sloping road from the metro station, so this may not be a good choice for those who may have trouble doing so.
It was easy to communicate with them through Airbnb, and they were quick to respond. The place was well equipped with all essentials. Tokyo was our last stop, so having a washer to do laundry was handy.
We would recommend this Airbnb to our family and friends, and return here on future trips.
