Nice little apartment located in a quiet area and walking distance to a couple train stations. Had no issues walking to Roppongi Hills and even up to the Roppongi area itself.
The apartment was clean and had everything I needed for my stay.
Checking in was a bit different than other places I've stayed at. The tablet in the apartment had connection issues and took a few times to upload my photo, but other than that it was relatively easy and straightforward.
