We stayed at Cristina & Olaf's for a month, we highly recommend it to anyone traveling to Santiago. The location is perfect, the apartment was absolutely spotless and in perfect shape. Extremely accommodating, Cristina was always available. We had no issues at all. The apartment is nicer than what the photos show, the area is both central and quiet, which is a great combination. If you are sitting on the fence about it, do choose it, you will not regret it.
