The apartment was a wonderful home for a week in Barcelona with our 2 year old.
The location is fantastic. Not more than a 15 min walk anywhere. A metro and regional rail around the corner. Plenty of cafes and bars right there. A mini-mart for basics next door.
The apartment was a good, not huge, size. It was very comfortable for two adults and a toddler. The kitchen was well stocked (plates, pans, utensils) and we made breakfast and some dinners easily. The Nespresso machine was great too (though we needed to buy the pods).
The rooftop pool was so great to take a break (during nap time) or at the end of the day. At times, the pool had a few families with kids; other times, groups of friends or couples hanging out.
They provided a pack and play crib and sheets. We moved it between the living room and bedroom depending on nap/sleep time.
We'd definitely stay there again and recommend it to families who want a bit more space and flexibility.
