Loved our stay here! We were a group of 5 people and stayed for 10 days. Communication with Miko was great! She always answers super fast and friendly.
The location is great! The Minowa Metro station is only a few minutes away and you come by a seven eleven on your way there.
The walls within the apartment are pretty thin, so you will here the rest of your own group. However, the other groups in the building didn’t bother us.
If you need complete darkness to sleep, this accommodation probably isn’t for you. The blinds do next to nothing and you will probably be woken up by the sunrise. This gobes you plenty of time to explore Tokyo tho :D
