Sayuri's place is centrally located in Shinjuku. It is about a 5 minute walk to a main station that's connected to all the major city stations including Shibuya, Harajuku, and Shinjuku. The main city and shopping areas are just a 5 minutes walk away as well. There are various konbinis located near the apartment and it takes less than 5 minutes to walk to (also on the way to the train stations!).
Sayuri the host was very responsive and check in was easy. We were expecting a reception area but it is a self check-in system that made it even easier. We appreciated the home and cleanliness. We just thought the pillows and mattress were flat and non-supportive. Overall, an amazing stay and experience in Tokyo.
