We were very happy with our stay in Santiago's apartment. We got a very good value compared to the huge hotel prices in Sevilla. The apartment is very close to a big shopping center, a metro station that goes to the city center (3 stops), bus stations and shops. Santiago also has some excellent tips for restaurants both close to the apartment and in the center. You should try them for sure.
The apartment is very clean, the bathroom is completely new and the shower is excellent. The kitchen has the basic equipment to cook breakfast and quick meals (there is no oven, but there is a microwave). For two people eating out a lot is was ideal.
Santiago is very helpful, we had good and fast communication and his instructions made it very easy to find the apartment.
