Putting a family with small kids into the middle of Poblenou festival is generally not a great idea, putting us on the 1st floor with windows directly facing two noisy streets and walls made of cardboard is awful. There was continuous noice and music until 3am and later on most days during our stay which made sleeping unbearable.
A 5-star behavior for Lugaris would be to tell us in advance that there is a festival so that we can reconsider. A 4-star behavior would be to make sure that we get a different apartment further from Rambla del Poblenou (assuming there are multiple apartments). A 1-star behavior (and that's what happened) is just sending us there telling that this is a quiet apartment.
