Casas Del Rio is an amazing place to stay. The host is fantastic, the staff are always available and have helpful hints on where to go.
The apartment itself is clean and close to everything you will need to make your stay in Santiago a great one. You have a great variety of restaurants to choose from close by and the neighborhood is calm, safe and the subways are a short walk to get to anywhere in the city.
Overall I loved Santiago and Casas Del Rio was a huge reason for that. Definitely will be coming back to Casas Del RIo.
