We stayed at Masami's for two weeks. Everything was super clean and organized. The instructions to get to the apartment were fantastic.
The location is really good, about 8 min walk to the metro, with a 24-hour supermarket right next to the exit. Really convenient.
We were supplied with clean towels and toileteries which was also very useful, and the bed (although not very big) was very comfortable. She even bought a bag of Japanese snacks for us.
There is a shopping street and plenty of restaurants nearby and the neighbourhood felt really safe.
