I recommend staying at Fabio´s with all my heart! My sister and I had such a nice stay at his lovely appartment (which looks exactely as in the pictures). He welcomed us, there was a bottle of wine as well as olives waiting for us. Even from the outside, it´s such a pretty house, with lots of plants and the typical Andalusian tiles. The place itself is clean and nicely airy, a fact not to disregard in hot Sevilla...The location is also fabulous: no tourists, but lots of nice cafés and bars in the neighbourhood. It´s exactly what you want if you´re looking for an authentic experience.
When we had to leave, Fabio stayed at home to say goodbye, made sure we´d get to the right bus station and everything(right - all the time, Fabio would be responbsive to our question about good bars, directions, etc.). Pure heartiness!
