Location is perfect. Restaurants on all sides of the neighborhood and a ten-minute walk to Sagrada Familia and maybe 15-minute walk to las Ramblas. The view from the balcony and living room is very atmospheric. The mountain with the church on top is fun to look at throughout the day.
We slept late each day (10 or 11am) in an attempt to stay on United States EST and also so we could convince our children (4 and 8) to go out to dinner after 8pm. The apartment is quiet, facing the inner courtyard of the block and not the busy road out front.
Our kids complimented the Television. It has all the apps they needed to watch a couple programs each day to make-up for the 8 hours of walking we inevitably marched them on. Two subway stations are nearby, as well as a bus that heads to the beach. Our 8-year-old enjoyed the bedroom with the built-in drawers and closets in the front and the master bedroom and smaller two-single-bedroom are next to the bathroom.
We cooked a little and did a load of laundry.
Overall we had a great family experience in Barca!
