Andreia was so kind as to let me check in a bit earlier as her partner was there when I arrived. Her partner showed me the place and kindly explained everything (we conversed in French/Spanish).
The room was great for me (as a single guest) and had a heater which I choose not to use much. The bathroom was clean and nice to use but I didn't see a way to lock it (which was not an issue).
The flat is on the 5th floor which I enjoyed.
Thank you very much!
