The apartment was small but very clean, well equipped and very well located. Wi-fi was very good, neighborhood was safe. When we arrived in Chile, our cell phones did not work but there was a nice café/ice cream shop right in front of the building where we could find a wi-fi spot to call Hector. He sent someone to hand us the key in less then 10 min!
If you are going to buy food for breakfast, I suggest going to the supermarket in Costanera Mall (Jumbo), which is much better then the one near the appartment.
