We very much enjoyed our stay at the Paralelo Apartment. There was plenty of space for a family, and it is close to public transportation, loads of great restaurants, and markets. La Rambla was about a 15-minute stroll away, and the Montjuic Funicular is just a few blocks toward the sea. Just a bit past that, on Saturdays there is a great farmer's marker at Jardins de les Tres Xemeneies. Check-in and check-out were easy and friendly, and the place was clean with a new kitchen. For its location on a busy street, it was relatively quiet with just the occasional sounds that one would expect of a large city. If Poble Sec is on your radar for staying in Barcelona, definitely consider Paralelo!
