I stayed for one month at Veronica's apartment and had a great experience. Veronica was very welcoming and had excellent advice about Santiago (including places to visit, how to stay safe etc.). The apartment was very well-kept and clean, and with a great location (walking distance from the Tobalaba subway stop, the Costanera center, and restaurants on Isadora Goyenechea). I would highly recommend if you are a solo-traveler in Santiago to stay with Veronica - she helped make my transition to the city seamless.
