We found Maris apartment after our hotel was cancelled on the day of arriving in Tokyo. At 6pm ish we started to try to find new accimodation. After booking, Mari was extremely responsive and we were in the room by 8pm.
Unfortunately the room was too small for us (3 adult males with lots of baggage) so it wasn't feasible to stay here. Mari allowed us to stay one night but cancel the remainder of our stay, and provided a full refund very shortly after our request. Mari was extremely helpful and very quick to respond which made this whole process very easy for us, and allowed us find a new place the next day
