Very good apartment. Really enjoyed staying there and I do recommend it.
However:
1) WIFI is mega slow and mostly can’t be used much. Even for streaming some music.
2) more ALL SORTS OF cleaning products should be made available, especially for stays of more than 2-3 days.
3) there are too few glasses, plates and utensils to be really able to make any use of dishwasher (by the way: when one opens it, ATTENTION: the doors do not have any breaks and fall immediately down hitting hard legs and feet while being SERIOUSLY heavy!!!).
Enjoy the apartment and beautiful Barcelona!
