Mar is an excellent host. Great and fast communication. Appartment's location is good - quiter than the central part of the city, public transportation stops are very close, within 3-4 minutes from the appartment - metro line L2 will get you to La Rambla within minutes, Bus 45 will drop you off right on the beach and Bus 92 will get you directly to Park Guell. There are a lot of good restaurants and super mercats nearby. Mar allows flexible check-in/out times for which we were so happy. Thank you Mar!
