The stay at Beatriz's place was a blast. It is a nice, clear and cosy apartment in the heart of Sevilla, minutes on foot to the best cafes and restaurants. Supereasy to get there from the trains station too (a bus stop 100 m from the house). Beatriz was very easy to reach, quick to answer and helpful. When I arrived to the apartment not everything was in perfect order but when I wrote her, she organised a cleaning lady that arrived in several minutes. She was out of town so I had whole place for myself. If it is not the case, just have in mind that the room you are going to sleep in is very tiny and you would need to use common areas to feel at home. I can totally recommend.
