We enjoyed our stay at Javier & Maribel's apartment in the Triana neighborhood of Seville very much. They met us at the door and graciously showed us around their flat. It has access to a roof top deck with a table & chairs and a nice view.
The Triana neighborhood is directly across the river from the historic old town and has a lot of small local places to eat & drink. We liked it so much we extended our stay by an extra day. If you want a taste of Seville with easy access to the old town I would highly recommend it.
