My chilean husband and me, from Germany have a lovely apartment, very close to Public Transport, Sights, Art Galleries, Cafes, Restaurants & Bars.
There are plenty of grocery stores and supermarkets in a very short walking distance. Barrio Italia & Bellavista, very hip districts lie also in a 10 min walking distance.
Close to your flat are nice parks and green spaces to relax! But just strolling around in our nice and coziest of Santiago´s neighborhood will be a great experience.
