We had a very pleasant stay at G Stays. Staff is friendly and helpful and check in information could not be more clear, making the process simple from the airport to the Airbnb.
The Airbnb is well located, about a 10 min walk to the Shinjuku metro station. Close to convenient stores and restaurants and about a 6 min walk to Golden Gai.
The room itself is simple and small, which is pretty standard for Japan. Very small bathroom and shower which we have become used to in Tokyo. Bed was a little too soft for my taste, but all in all the room was OK.
For travellers looking to get around easily, this is a good place!
