Pia's place is about 30 min walking distance from the Alameda Bus Station and about the same to the Plaza de Armas in the centre of Santiago. It is also on the side of the city closest to the airport. I found the location very convenient. Located in a modern building with a portero and full security it is perfect for the solo traveler. An added bonus is the full breakfast provided, it will keep you going all day! Pia is the perfect host.
