Joaquin was a great and very responsive host - we never met in person, but he provided a seamless check-in/check-out experience for us. The location of the apartment can't be better - situated in one of the most beautiful part of the city, right in the heart of the old town, just a few minutes of walk away from the Metropol Parasol (and a few more from the cathedral). Everything worth seeing and doing in Seville is within walkable distance of the apartment - we never took any taxis while there. The apartment itself was tidy, well-supplied and nicely decorated.
All in all - I can heartily recommend this apartment. I'd certainly stay there again if I'm ever back in Seville!
