We found the apartment exactly as described. The location is unbeatable, right in the centre of Santiago,5 min walk to the Presidential palace and the nearest subway station. Lovely view of the snow- clad peaks of the Andes in a distance (well, if the air is not full of smoke like during our visit, due to the catastrophic wild fires in the surroundings of Santiago).
Check-in was easy. Patricia's mother welcomed us in person at the spotless clean, well appointed apartment.
Well- functioning wifi.
Only negative experience were some neighbours who watched non-stop screeching tv- shows until 3-4 am - every night. Nothing much even the best host can do about it!
