Worth to stay if you want to oversleep in a private room in the very heart of bcn for almost same price as for shared bedroom in a hostel. Although the apartment has a bit oldish and used look and there is no really welcoming common space such as a living room or dining area, it has a nice vibe and is absolutely clean and well prepared. Constance is very nice and easygoing, she answered within few minutes and accepted me even the same day and with check-in after midnight. She also allowed me to store my luggage there till the afternoon wnen leaving. Thank you, Constance!
