Maria has been very kind, she let me decide my check in schedule and gave me advice on what was worth visiting. The room isn't big, but incredibly cozy and lovely, and the bed is definitely comfortable (though there's no lock to the door). The same applies to the bathroom. The position of the house is also quite central, it took me 12-13 minutes from copenaghen station for reach it on foot and usually it took about 20 minutes to reach the center of the city; I kinda liked the neighborhood too, there's a park and a lot of pub, markets and so on.
Highly recommend.
