The location is very good, in the center of Barcelone. Sadly, we had only one spare of keys for 4 people, and everytime someone comes, you have to get downstairs to open the door of the building (and the flat is in the 6th floor)... really annoying !!
The floor was dirty. We paid an extra 20€ because we arrived after 8pm. Otherwise Llorens is very polite and answers quickly, but doesn't speak English (but understands it).
