My husband and I stayed in Ewa & Pau's place and had a wonderful time! This was probably our best airbnb experience so far! The place was super clean and freshly renovated and looked just like in the photos. It was also in a perfect location, with a lot of transportation nearby, but also in walking distance from many of the places we wanted to visit, and yet located in a very nice quite area, with many nice local places where you can grab a bite.
Ewa was very helpful and flexible with our check-in and check-out times, and had no problem meeting us to give us the keys and some basic information when we arrived at midnight! She also provided us a very nicely organized booklet she had made for the apartment, which included any information we could possibly need for our stay in the apartment and our stay in Barcelona in general. We felt we were in very good hands and would definitely love to visit again!
