It's nice to have space to spread out in the middle of the city. Mom and dad in the main room, 2 teens shared the room with twin beds. Comfortable large central room. AC. Balcony with the quiet interior of the block to sit and have morning coffee or end-of-day beer.
Kitchen supplies were sparse - plan on shopping right away for very basics (eg, coffee). Easy to get to all the great Barcelona spots.
The setting itself is somewhat spare, some AirBNB's we've stayed have a "luxury" sort of feel, this does not. But the other amenities make it a good value.
