Soledad is a lovely lady and tries really hard to make your stay as enjoyable as possible.
She responded very quickly to any questions we had.
The location of the apartment is fantastic. It is on the 24th floor and has a spectacular view over the city and the distant Andes mountains and right next to the Metro station Santa Lucia making it very easy to move around the city. It is a 10 minute walk to the area Lastarria which is full of good restaurants and bars. Most of the city sights are within walking distance. Also several wineries are easily accessible via the Metro. Cousino Macul winery is a must tour if you're a wine lover.
The only downside to our stay was the apartment could do with some refurbishment.
I did mention this to Soledad and if that was done the apartment would be superb.
We found the area to be safe and the apartment block has a 24 hour concierge.
