Claudio is very, very accommodating: he was able to change my check-in time as well as my check-out time. During my stay, he was attentive to my needs and was able to share everything I needed during my stay. Communication was almost instant. As far as location: awesome. There is a gym where you can get a free pass for 10 days, which was great. Also, his apartment is located on the edge of Bellavista and Lastarria, which gives you the opportunity to do many things.
