We had a great time staying at Paco's place. It was a beautiful, clean apartment, in a prime location (close to the Cathedral, the Alcazar, and dozens of restaurants/bars/cafes) - and we were woken up by peacocks twice!
To be noted, Paco offers a taxi service to the train station, it costs 13 Euros which may be more than outside cabs but worked out very conveniently for us. Paco was a gracious and talkative host and it was enjoyable to talk to him as he has a lot of travel experience of his own. We would certainly recommend this place to people visiting Sevilla!
