I really enjoyed my stay at Maria's apartment. I was in Seville for a business conference, and this was a perfect place to stay, being just ten minutes walk from the Cathedral and other places I needed to get to, and in a nice and quiet area.
The flat itself was just right for a 4 day stay - comfortable bed, convenient kitchen (with Nespresso machine), and clean bethroom, with a very powerful shower.
I'd definitely recommend staying here!
