Everything was great, i definitely recommend the apartment. Communication with Luis and Alex was very easy, the location is great for visiting Barcelona - a lot of restaurants around and everything is walkable from there. Apartment is pretty spacious and has its own clean bathroom and balcony. There is all the necessary equipment at the kitchen, which you share just with one another room. Comfortable pillows and bed.
WiFi connection is very fast - over 200mbps, which is over than enough for any purpose.
