We were really happy with our choice. Charlie's apartment is great, as it is shown in the pictures: big, nicely bright, warm and modern, with a great view of the city and Los Andes 'cordillera' in the background. The balcony is a nice spot to watch the sunset, especially if you go in a warm season.
Location is the key. The apartment is in a really quiet and beautiful street. Also, very close to the Costanera Mall, restaurants area and subway stations.
Charlie is a great host. He showed trust from the beginning and made sure we had all we needed along the week we spent there.
Definitely we are going to make the same choice in the future.
Thanks a lot Charlie.
