My wife and I had a fantastic time in seville staying in Leonor's apartment. It was spacious, very clean and lots of big bright windows. Leonor and Diego were very welcoming giving us maps, and different places for food. Leonor even gave us lemonade after our long travel which was really nice to have.
The apartment is located near many restaurants and bars and even the seville bus city tour is located nearby. The doors/windows did a great job of isolating any noise coming from the street. However over night there were some parties that went on till 2-3am and you did still hear the noise. We slept thru it for the most part but if your a light sleeper you might have issues sleeping from the noise.
