I've reserved two days before arrival and David was really fast with the answer to my question. everything was set up for my arrival.
Aparment is big, very well equipped and working. clean. no problem with the wi-fi. nice bed. elevator in the building. nice small balcony in the apartment.
The area is amaizing, 1 min. walking from Plaza Universitat, less than 5 mi. for the Ramblas and 3 min. to Plaza Catalunya. no better than this. restaurant, bar, shop, everything is close.
Definitely reccomended without hesitation. thanks again David.
