Very well placed in the City, with this location we visited everything we wanted walking a few minutes.
The appartment was very clean and everything we need was present. Joaquin couldn't welcome us but leave us very good and precise informations to get the keys easily.
One and only negative point : it's a little bit noisy early in the morning due to a bar proposing breakfast just below the appartment.
Nevertheless, my girlfriend and I trully recommend Joaquin and his appartment! And of course we recommend Sevilla which is a wonderful city!
