Cristian is a very attentive host. Whenever we had questions he responded immediately and was very helpful.
The reservation process was easy and since there was no guest arriving the day we left he generously allowed us to check out late.
The apartment is on the top floor of the building and has great views of the west side of the city (and Cerro Cristobal). The swimming pool is one floor up and has unbelievable 360 degree views...including the Andes. There is no furniture on the roofdeck but he provides a generous amount of towels so you can lay out up there.
We couldn't hear the neighbors, though being in the heart of the city you will hear street traffic. Speaking of being in the heart of the city, the location can't be beat. You're literally on top of a subway station and have easy access to everything Santiago has to offer.
The water pressure in the shower is great, too.
Although small, the apartment is laid out well enough for two people.
