This stand-alone house was a great choice for our three-night visit to Tokyo. I would strongly recommend using this as a base for a longer stay in Tokyo, especially if you are traveling by car or you expect visitors by car. It has good access to both Daitabashi and Sasazuka stations on the Keio Line, making it very easy to get into Shinjuku and Shibuya, or out to Kichijoji or Mt. Takao.
The property is well equipped in terms of facilities, with a good kitchen and bath/shower as well as washing machine. It also has a spacious rooftop terrace. Possibly the only disadvantage of this house is noise from the major intersection nearby, but generally we didn't find this a problem. The host has put a lot of effort into details that will make your stay more convenient and enjoyable. For example, in addition to WiFi at the house, guests can use a mobile WiFi router when out and about in Tokyo. There's also a good guide to local eateries. My personal recommendation is Maison Bretonne / Bistro DECO, which is about a 10-minute walk.
Pre-stay communication with the host was very smooth, and listing details were accurate.
