Felipe is an amazing host. From immediately confirming the reservation, to replying to all of my questions right away, Felipe was very attentive. He waited for me at the apartment when I arrived, and he even offered to help me arranged a taxi to pick me up at the airport. When I got to his apartment, he was there to show me the place and how everything worked. He also gave me directions to the places I wanted to go to, and how to get to the subway and supermarket.
Felipe's apartment is just as you see it in the pictures. The bed is very comfortable, the apartment is very clean, and the view from the terrace is spectacular. If you are a light sleeper, You can hear the traffic outside even with the windows closed, but as long as you get some earplugs, you'll be fine.
The apartment does have a washing machine, but it's broken. However, there's a laundry room in the basement of the building. You'll need coins to use the machines.
I'd definitely recommend Felipe's place to anyone who is visiting Santiago. The location is great and Felipe is a fantastic host.
