This is a great place to stay when visiting Barcelona, especially if you want an area outside of the busy hustle and bustle of the touristy areas. The apartment was clean and we were able to easily access the roof top deck for pre-dinner drinks. Damien and his staff made the stay even better. He answered my questions quickly and was in constant contact with me leading up to and during our stay. One of the best parts of the building was that there's a market right next door to buy food, and you have breakfast included from a cafe around the corner. Our apartment had AC in the main area but not in the bedrooms. It was cool at night, even in June, and the provided fans made it even cooler.
Friends of ours stayed in a different apartment in the building and had AC in the bedrooms, so it just depends what apartment you are in. I would definitely recommend staying in this apartment and I would stay again in the future!
