Las Condes is an upmarket suburb of Santiago - very clean and safe but you need to make a journey to get downtown. We loved the view of El Carbon and Manquehue mountains from the apartment - so much so that we climbed both of them. The apartment and apartment block was very well run with 24hr concierge, pool and basement parking. The concierge staff were very welcoming and friendly. We did find the traffic noise from Avenida Kennedy quite loud but we quickly got used to it and it didn't spoil our stay.
