Mari & Petz did everything they could to make our stay enjoyable even before we arrived. Petz even did research on restaurants for NYE that could accommodate our large group. The apartment was immaculate and the rooftop breakfast was a great way to start the day. The wifi was also very reliable, which helped in booking tickets to museums and other research. I would recommend them to any friends visiting Barcelona especially a group or a family. It really made it easy to enjoy the city together.
