I stayed for a week at the beginning of my Erasmus semester. Carmen was a wonderful caring host. She helped me getting to the house, explained me the room, the kitchen and so on. When I had questions she tried her very best to help me.
The whole flat is very clean, there was a fan, the room was big enaugh for one person and all the luggage.
Heliopolis is a little bit apart from the center, that could be the only problem.
Carmen, thank you for this great first week in Seville. :)
