We had a wonderful time at César's Airbnb. It was super clean, cozy and the appartment had all the amenities we needed. The location is just outside of the center (15min walk), which was quite doable and leads you past a few streets with many options to eat (e.g. Almeida Hercules & Calle Feria). A bus stop is 2 min from the apartment which provides easy connections to all of Sevilla.
For any questions or issues we had, César answered them promptly. The apartment is suited for couples and/or even families with children, however be mindful of the stairs. A definite bonus is that we were able to use an app to open the building and appartment door. No need for keys!
When we come back to Sevilla, we'll definitely stay here again!
