This is a beautiful apartment in a gorgeous setting -- the building's courtyard is one of the most tranquil places we've seen -- and it's hard to beat the location. The street is beautiful and you can walk anywhere in Seville from there. Jorge was responsive and even dropped off a bottle of wine during our stay.
One thing to note is that the apartment is a tight squeeze for two people, and I can't even imagine fitting more people in there. There was barely enough hot water for one person to shower, and absolutely no hot water for the second person. This apartment is great for a solo traveler, but tough for a couple or group.
