Raul is a welcoming and accommodating host, had no issues with our late arrival and had more information and help on offer than we could want.
The place is great, very modern and comfortable. It does get cold and the heater really isn't quite up to warming the space properly was the only real hassle. The kitchen is small but has all the basics, we cooked dinner each night without a hassle.
The area is fine, got a little rowdy after a football game but so does all of Santiago..! Concierge security is reassuring, decent supermarket just near Plaza de Armas a few blocks up, all in all a central and very convenient spot. Easy to find too, Google street view in advance if you want but no need.
Happily recommended!
