Nelson's apartment is an excellent choice in Las Condes. It has tons of windows and is bigger than many other units in the area. the location is very lively, close to many restaurants and walking distance from metro and the Costanera Center shopping mall.
Nelson is very nice and helpful, and flexible. He allowed us to stay a bit longer during check out so that we didn't need to wait at the airport, for example. The communication and check in was very smooth. Thanks Nelson!
