The apartment is is nice, clean and very spacious for two persons. Also it is well-equipped with all essentials. Moreover, the location is perfect: very close to the local hotspots like Alameda de Hercules and Mercado de Feria and at the same time in a street that is quiet at nights.
We didn't meet Isabel in person, but were welcome by her friendly sister, who also gave us an introduction to the most important places of Sevilla. Communication was very fast and unproblematic.
