I would not recommend this place for a family stay.
Pros - only good thing is location! Just off Las Rambla, and all the busy are of Barcelona.
Cons -
1) even the location is great, be prepared to see homeless people sleeping in alley of apartment main door
2) there is always a foul smell in alley of main door
3) apartment needs serious upgrade/renovation. Sofa bed is very uncomfortable, sagging, and noisy. Flooring and countertops have chipped surfaces, dining room chairs have tears
4) I was prepared for a bit odd check in process, based on reviews, but I couldn’t register myself at automated check in machine until I called someone, they were able to resolve quickly, but that just shows lack of process.
5) communication with apartment is not very clean, many times they won’t respond to email or Airbnb messages
6) Air conditioner exists just to check a box, it hardly cools place, area where two twin beds are- stays warm throughout
Maybe if location outweighs everything for you, you can go to this place, I won’t recommend this place
