We are a family of 3 adult couples. This was our first time in Barcelona, and we were thankful for Milica's friendliness & professionalism, and the lovely apartment! Tiny European elevator but necessary for those who don't want to walk up 5 floors. Spacious apartment with a clothes washer & dryer, and two A/C units! Cool view of the top of Basilica Sagrada Familia. The traffic sound didn't bother us at all. The Airbnb description is accurate, including no smoke alarms or carbon monoxide detector. (Milica does provide a fire extinguisher; upon arrival, know your emergency exits, incl the rooftop.)
The location is convenient, in walking distance of a large supermarket, pharmacy, literally next-door store for general household items (cosmetics, travel-size items, misc), ATM, pastry cafe, restaurants, bus, and the metro station at the Sagrada Familia - easy walk. For a reasonable fee, Milica picked us 6 up, & dropped off, at the airport, with 3 large & 3 carry-on suitcases. We had a 9:30pm arrival, tired & hungry, so it was nice to walk downstairs & around the corner to a welcoming tapas restaurant, Ole Mallorca. (Their sparkling water wasn't salty - surprised to learn this salt-taste at other restaurants; safe to order flat water). Delicious intro to Barcelona!
