We used the Natural Ellipse house as our base for a week in Tokyo and were very happy staying there. It has plenty of room for a couple. The layout was a bit hard to decipher from the listing description: there are two apartments in the building and this one is the bottom two floor. There's a bedroom, a living/kitchen space, and a bathroom that's open to the living space. It was very clean and minimal in decor. Taeko is a great host: she met us at the apartment, showed us around, and shared recommendations of local restaurants. There was a slight issue with the shower during our stay, but Taeko had it resolved very quickly. We did not have issues with neighborhood noise but did notice that the place is surrounded by bars and "love hotels". As with most of Tokyo, it was a clean area and relatively quiet. We'd recommend staying here!
