Our stay in Sevilla was amazing, and the apartment is very well located, you can walk downtown (aprox 15 min) or take the C5 bus. The place is also within walking distance of the Hercules square, where there are lots of restaurants. The apartment is so nice, there is a beautiful patio in a Seville style, and there is everything you need in the apartment, if you need anything else you can contact the owner which lives upstairs. This is a ground floor apartment, so no need to climb stairs. On the inside of the door there was also an inside lock, but the neighborhood was really safe, and there were 2 more doors to get into the apartment complex.
Didn't get to meet purificacion, but met her son, who was really helpful when we needed.
