Nice flat at a great location! Near 2 different metro lines and walking distance from many things including the Sagrada Familia. The self check in and ability to open the door through a link was extremely convenient as were were a group staying there, the link only didn't work once but the host was available to answer our message very late in the night which was amazing! In general, the communication was quick and fantastic.
The flat is nice overall and we were extremely grateful to find a place that accepts dogs. The flat could be improved slightly as many things felt a little worn and old like the mattresses, the pull out sofa, and the AC in the living room which barely worked. The lack of AC in the 2nd bedroom was a little inconvenient for one couple but manageable. The place was generally clean and there were extra towels and sheets provided, a coffee machine, fridge, and a generous bottle of cava! Overall a decent place to stay, especially if you want to find a dog friendly option in Barcelona :)
