The apartment has very comfortable beds and is a good size for a couple. It is in a good location with lots of eateries around, several coffee places as well as different transportation access. It has everything you need for a short holiday if you need a basecamp for your exploring in Tokyo.
We did have some difficulties getting in with the electronic keypad on the door but our host was easily contactable and maintained constant contact while we sorted it out. They were able to address the issue and resolve it quickly.
