We had a great time at Maria and Carlos place.
The communication with them was super easy and quick.
Place looks even better than it does on the pictures, it was super clean and is very well equiped. The apartment is very quiet but at the same time well located in lively neighbourhood.
Self check in is super convinnent and quick.
I would absolutely recommend to stay in Maria and Carlos apartment and definetly come back to stay there when in Sevilla again.
