The apartment is in the perfect location and it’s very spacious, absolutely suitable for a family.
However it was very dirty and we are disappointed about this fact. Especially the bathroom! Please take note about that!
And something else which there’s nothing the hosts could do about but I will write it for your future guests to know - if you are visiting Barcelona in the weekend keep in mind that this place is extremely noisy. We couldn’t sleep at all on Friday and Saturday night. There is not good window insulation.
