Great stay overall. Has all the basic amenities one would need and the host was very kind as well; communicating from beginning to end and giving directions to the place and showing the place around which really is a great place! I was worried there might be a lot of bugs since this place is literally located right next to the park (Parc Güell), but the place is sparkling clean and even during the summers I would imagine this would not be a problem as the windows are double lined and AC for each room (even common areas). The place itself was really quiet as well so would recommend for visitors that want a peace of mind while exploring Barcelona (not for the nightlife seekers as it is a bit far from the center, but doable nonetheless).
Would highly recommend if your main point of stay is to explore Parc Güell and for a peace of mind.
Would definitely book again!
