This is in reality a small hotel. One single person bathroom is shared amongst the entire floor, six or seven rooms. Thankfully I didn't run into problems wanting to use the bathroom at the same time as someone else. But it would have been a big problem if someone else was using the shower when I woke up early to get ready for my flight. The rooms do have a small sink though so you can brush your teeth and things in your own room.
If you're a light sleeper, you may have trouble here. You can hear pretty much everything going on outside the window and in the neighboring rooms.
Overall, it isn't a place you would want to spend much time beyond sleeping.
