The location of the airbnb is great. The Camden Market and the underground station are very close. We basically just needed a room to sleep, so the airbnb was enough for us.
The shared bathroom situation was also good. They were cleaned everyday but for me personally it was still a bit uncomfortable sharing a bathroom with a bunch of strangers. But that's just personal preference.
The only negative thing was that the wifi didn't work properly. It was quite slow and the connection wasn't great. But since we weren't in the room much, it wasn't a big issue for us. I definitely recommend staying here if you are on a budget but still want a room near central London. Of course it's not the most luxurious place but it has everything you need. The communication with Justin and Mark was also great!
