We absolutely loved staying in Paco's place -- it was spacious, comfortably decorated, and perfectly located as a base to explore Sevilla, with a breathtaking view over the gardens. Paco was a great host, very communicative, warm, accommodating, and flexible.
One note of caution: we heard a very loud squawking sound from the park late at night and early in the morning during our stay, which was a mystery until we peeked out the window and realized it was a peacock on the roof of our building next to ours! We found this hilarious and considered it the highlight of our trip, but I would recommend bringing earplugs just in case. :)
