Only positive things to say! Location of this flat is perfect (though because of the very central location there is some noise coming from the street on weekend night because of the parties, but you should anyway be down there as well) and the room and the flat looked nicer in reality than in the pictures. Whole apartment was very clean and it works very well that only two rooms share the kitchen and bathroom. I never had to wait for my turn, and I barely noticed that the other people were there.
Ana was super friendly, even at 4.30 am when I woke her up because I was in trouble.

Only thing I didn't love are the loooong and steep stairs you need to climb. Don't take this room if you have bad knees. But I would love to stay here again.
