We have slept here for 2 nights. The room was small but comfy. The bed was as well comfortable.
The flat itself is like a little hotel: everyone get the keys of its own room, and some common rules are in place to prevent noises or disturbances to the other guests.
Bare in mind that in the common area you will not be able to cook. A microwave is at your disposal altough. You can buy coffee/tea and some other beverages directly in the flat.
The location is extremely central. It may be noisy at night. Alba was kind enough to give us some earplugs
