Marta and Paul's apartment is in a great location, walking distance to most places and very close to the metro. Apartment was very clean and had a good view and balcony and was quiet every night we were there. Marta and Paul were great and let us leave our luggage two hours past check out on our last day so we could take advantage of our last hours in Barcelona. One thing I would recommend is bring extra blankets if you tend to be cold and extra towels if you are there more than a few days. Overall definitely recommend if traveling to Barcelona!
