We stayed at Mabel's place for seven nights, the apartment/loft was great
It is very well organized, furnished and decorated and fully equipped with everything one needs. It even have an underfloor heating system that was very helpful as we were there in the winter
The apartment's location in excellent, five minutes walk from the Costanera shopping mall and the Sky Costanera tower and eight minutes walk from the metro station
Mabel and her husband are very nice and helped us with everything we needed at any time of the day (or night)
Next time we will go to Santiago we will certainly try to book their place again!
