Raquel and Marco's apartment is beautiful. It's just as the pictures described, with a large living area and 3 comfortable beds.
When we arrived, Marcos met us with fresh supplies, including coffee and tea, which was really great! He helped us with our questions as well as directed us to the Metro which is just around the corner.
The apartment isn't central to Barcelona but the Metro makes it trivial to get anywhere in the city quickly and cheaply. The Sagrada Familia is only 3 stops away, and other attractions are within a 20 to 30 minute ride.
The neighborhood is very nice and quiet, we felt very safe and had an easy time finding food and other items.
Overall an excellent experience with great hosts, in a lovely apartment, in one of the best cities around. Don't miss it!
