Sergio contacted me few days before arrival informing that he'll be away that day we arrive but his partner Natalie will meet us and provides all info. I called Natalie in metro and she kindly explained me how to find the place. It was really easy as the apartment is only few hundred meters from Sol metro station and to get there is really easy. The apartment is bright, clean and well equiped. The possition in the city is really great as you can reach all spots by foot or just take a metro from Sol if needed. Highly recommended!
