The apartment was immaculately clean, and had all the facilities needed for a 5 day stay. The transport links are great - 20 mins to Gotanda and from there easy access to Shibuya, Harajuku etc, and 10 mins to Kamata and from there onto Tokyo centre or Yokohama. Local grocery shops on the quiet street.
For those who read the reviews and worry about checking in, it’s really not difficult.
First you’ll need to digitally upload a photo to the website when you book - you’ll get a link to do this. You’ll be emailed the front door pin and your room pin a day or so before staying. At the property itself you just take selfies and fill in your details. The lobby door is open all the time. I suspect those who had difficulty perhaps did not check their emails but it really is not hard!
