We were traveling with 2 adults and our 3 kids (ages: 4, 2, 0). We enjoyed our stay in Chris's apartment, very quiet place as it is in the back of the building. Our flight arrived early and we were able to get access to the apartment almost right away. This was a larger space than we thought which was great for our oldest to run around and play. The bedrooms are all nice, the third is a little far from the master so best for an older kid, but our 2 year old did fine that far away. Kitchen and laundry were adequate; the dining area was nice with windows to the courtyard. Both the coffee and dining table are glass top with sharp corners, careful with kids. There is an elevator which was nice since it was on the 3rd floor, but it is old and pretty small - but we still fit a collapsed double stroller in it.
Overall location was great. There are several grocery markets on the block. A bakery literally next door with AMAZING chocolate croissants, and a nice chocolate shop half a block away. Some gauge of distances:
BY FOOT (walking with 3 kids/double stroller):
* Barcelona Cathedral: ~20 min
* Casa Batllo: ~ 15 min
* Casa Mila: ~ 10 min
BY CAR
* Airport: ~20 - 25 min
* Parc Guell: ~15 min
