Outstanding apartment, outstanding communication, and outstanding location.
Marta's apartment is perfectly set up for families and for people who want to see the sights of Barcelona, and enjoy the city without being stuck on the crazy tourist area in the gothic quarter.
I enjoyed excellent, super quick communication with Marta on the few questions I had.
The apartment is conveniently located right on the border of Gracia and Eixample with tons of restaurants, coffee shops, bars, and supermarkets nearby. For context - Parc Guell, Sagrada Familia, the Gothic Quarter and El Ravel, and even the beach are all within walking distance - we only took taxis or public transportation to and from the airport.
