When we checked in, the apartment was even beyond our expextation. It was so clean, got everything we need (especially the washing machine) and very centre-located. We can get all the famous attractions just by walking, the furthest one can be reached by 20 min on feet. About the A/C, the flat has 3 A/C, one in the double bedroom, one in the main room, and one is in the hallway (opposite to the smaller bedroom), which helped us overcome the hot summer in Barcelona. Overall, my family is happy with this Airbnb experience.
