On our trip we stayed in airbnb in Barcelona, Sevilla and Madrid and by far this was our favorite. A wonderful location right next to the Cathedral, with access to plenty of shops, cafes, restaurants, and sightseeing! The apartment was very clean and well outfitted ---- we had everything that we needed. The roof top terrace was very nice --- it is apparently shared with other apartments in the building but we never saw another person. We sipped wine and played cards until it got too dark to see (there is no lighting on the terrace). Even though located in a central part of the old city with plenty of hustle and bustle, the apartment was very quiet. Prior to our arrival, Eugenio provided a .pdf document with a guide to the city, which was extremely useful. In addition, when we arrived, we found operating instructions for all the appliances, which was very helpful (although the instructions for the washing machine were in Spanish only). The owner/host was very accommodating with arrival times, and he was there waiting for us when we arrived. He took time to show us all of the features of the apartment and then answered all of our questions.
Of all the AirBnB apartments we have rented, our communications with Eugenio were by far the best. He will take care of you!
If we are in Seville again, this is where we would choose to stay!
