I stayed in early Dec '19 for 1 night in this room. Its a made for Air BnB / short term property. The property in a maisonette 5 minutes from Camden station is a series of rooms, 4 or 5 in total I think, with 1 toilet and 1 bathroom, no shared living room or kitchen.The room itself was clean and nicely decorated and the bathroom was fine.
This type of listing is fine for someone who needs a room for the night (as I did) or tourists staying in London up to 4/5 nights and who are OK eating out breakfast, lunch, dinner. The one negative was that the doors and ceilings were thin so expect to get woken up in the morning if you're a light sleeper as people start getting up.
The check-in details left by Justin were clear, there's door codes for the front door and your individual room. Don't expect a personal check-in at the property - this is not what these types of listings are about. If you're staying alone be sure to take your room code to the toilet/bathroom or you can get locked out.
