Fabulous place in an ideal location! My friend and I stayed at Onix' place for 10 days and everything went smoothly. It was great to be in a safe area with everything you need, from grocery stores to small cafes, tapas places, and fancy restaurants. Check-in was pleasant as Onix came to greet us with lots of good info about the area. Checkout was a breeze. The apartment is very comfortable with 2 big highlights: a view bringing lots of sunshine in, and an amazing terrasse. In warmer weather, we would have spent a good amount of time on it, eating the Iberico ham we bought locally and drinking to a beautiful city! The bed in the bedroom is very comfortable, the kitchen has everything to cook.
A couple small things that could make the experience top notch would be to clean or replace the sofa and cushions in the living room, and provide wifi. A router is available in the apartment but you have to buy a SIM card and install the connection yourself which we found to be technically challenging.
Overall, I recommend Onix' place and I would love to go back again!
