My fiancee and I stayed in Meridiano Sur for a week last July. We have relatives in Chile so we travel there almost every year, but this hotel is better than all the previous places!
The hotel is located in the heart of Providencia (maybe the coolest neighborhood in Santiago) and you can walk to a bunch of great restaurants, cafes, bars, and museums. If you want to try some good Chilean food, just ask the staff and they will give you the best tips.
The staff is really friendly. Their assistance was always fast and useful. We had a problem with the charger of my laptop and the girl at the reception desk lent me an adapter for the whole week!
The building itself is gorgeous: an old and noble construction, but inside everything is brand new. The decoration is outstanding as well: a perfect balance between traditional handicraft and contemporary design.
