My wife and I stayed at Alfonso's flat for a long weekend in Sevilla in May 2015. Alfonso was a perfect host. He was very responsive to all communications and was flexible in accommodating our arrival and departure. He also provided us with information/maps of everything to do in the area.
The flat was just as advertised and perfect for all our needs. It was clean, quiet and very well appointed. The location was very ideal and within walking distance to everything we needed. Absolutely no complaints at all.
