Good things first, Monserrat is a friendly host with good communication response time and the location is quite decent where the city centre is in walkable distance.
The room I had was absolutely basic. A single bed (not the bunk bed shown in the pictures), a fold-out table, a mirror and a build-in closet. That was all.
Now there were unfortunately also quite a couple of things I really did not enjoy.
1. Every day at around 6:30 in the morning, it sounds like a mouse runs through your room. I'm not kidding. It scared me the first time.
2. The room has no trash bin...
3. The apartment is very noisy where you can literally hear everything. Try closing a door silently or putting a plate back on the stack and you'll get a minor noise complaint. Basically don't do anything after 10:00 in the evening.
4. Water pressure is poor, so you have to flush the toilet twice to completely flush everything.
5. The showerhead hangs very low at like 1 meter above ground. Higher would have been better.
