Great experience. The apartment is really nice, the bedroom is exactly like in photos, really spacious and bright and you'll also have an electric heater (for winter). The bathroom is clean and comfortable too.
Rosemary and Antonio are really kind and helpful and they gave us a lot of good suggestions.

The positions is also really good. It's about 15 minutes walking from the Cathedral, Alcázar and Santa Cruz area (some of the main attractions), but you'll stay in a neighborhood full of bars and restaurants, full of Spanish people and students, more than tourists. That for me was a great thing (and it's also cheaper).

Finally, if you come by car, it's GREAT to have a free parking included. It would be a pain to find one otherwise.

In the end, I highly recommend Rosemary's place!
