Rosa's apartment was great! It was clean, easily accessible to transit, and the perfect spot to explore Barcelona. La Rambla, El Barrio Gotico, and La Sagrada Familia are an easy 20-30 minute walk, but the Gracia neighborhood itself is a main draw for this apartment. We ended up touring the city by day and hanging out in Gracia by night. This apartment allowed us to do both tourist-y and local stuff, and Rosa was a great host... I'd absolutely recommend to anyone taking the trip to Barcelona.
