We spent about a week at Felix's place. He sent us a list of things to do and recommendations and also left us a bottle of wine to enjoy. The location is perfect for exploring all things central to Santiago. Very walk-able but also a quick ride share to anywhere in the city. The best part of the apartment is the balcony. Being on the 11th floor, you are staring dead center at the San Cristobal hill and you can pretty much see the Sky Constanera on the right.
It is a very well equipped apartment. You will find everything you need for laundry and for making meals if you are so inclined. For those who are not used to the hum of a city, bring ear plugs.
Felix is quick to respond and was very accommodating to our requests.
