I recently stayed at Miguel's place and it could not have been better. Miguel's communication and hospitality are exactly what you want in an Airbnb host. Any questions that I had, he answered right away and even let us check in early as he did not have another guest booked the day before.
The apartment is fantastic as well and is exactly what you see in the pictures. It is in a great area and even comes with a parking spot!
I would highly recommend Miguel's place to anyone staying in Santiago.
