The apartment was very nice, in a great location right off the Ramblas and just above Placa Cataluyna. The air conditioning is in one bedroom, so you will need to leave that bedroom door open if you want the rest of the apartment to get any cool air, especially the other bedroom which is the furthest away and in the warmest part of the apartment (there is a standing fan which can help spread the cool air into the 2nd bedroom). The air conditioner had an issue where it started dripping in the night, and since it was right above the bed, it soaked through the pillow and mattress. However, I reported this and they came the next morning to try to fix things. They ended up moving the bed and calling a technician, who was unfortunately not available until the day after we left, but I appreciated their immediate effort to solve this.
Overall, very good experience. Thank you Luis, Remo, and Alex!
