Rosa's apartment is an amazing place for both shorter or longer periods in Sevilla.
I have been there for three months and enjoyed my stay. Rosa is a wonderful host: she took great care of me, our communication was perfect. The apartment was clean and well furnished from day 1.
The apartment is at walking distance from both the city center, the Torre Del Oro, el Parque de Maria Luisa (where you can find the wonderful Plaza de España) and the University of Sevilla.
I would choose it again.
