This apartment was great! We loved the proximity to the metro station and various coffee shops, grocery stores, bakeries, etc. The apartment was clean and well cared for and had everything that you could want for a stay, including a full sized refrigerator, dishwasher, and stove in the kitchen. The bed was comfortable and the apartment was well stocked with the essentials. It is equipped with an air conditioner and heater (although we only used the heater because it was cold when we traveled) and it kept the apartment very comfortable.
We would definitely return to this apartment when we come back to Barcelona!
