I would highly recommend this apartment!
The host has been incredibly kind and clear, both before, during and after our stay. She has made staying at an Airbnb very pleasant. The apartment was spotlessly clean, beautifully decorated (as shown in the pictures) and it had all the supplies necessary for a comfortable stay. We've arrived at the apartment with a very warm welcome and were every day happy to come back home to this little home.
What could be points of improvement? I'd say that the mattresses could be a bit more comfortable and the neighborhood isn't the best of Barcelona. These two factors didn't spoil our fun though. We still had an amazing time and really appreciated the effort Carmen took to make us feel satisfied with our booking - an example for other Airbnb hosts.
