As with any hotel, sound-proofing is always an issue. You can hear most of the noise in the hallways, people opening and closing doors. You can hear the dogs barking outside. We had the good fortune of being here when River Plate when the Copa de Sudamerica so we heard car honking and people shouting for a while but cannot blame that on the hotel.
Staff were all very friendly and helpful, made reservations, called taxi's and answered any questions we had. Clean and comfortable place. Close enough to main area that you can walk there easily but removed enough that you do not hear everything. The breakfast buffet was good, a lot of different things to eat. I think the thing people forget is that this is not in the US, so the style of cooking and food will not necessarily be the same. The packed lunch that you can order for the hike was solid and reasonably priced. Wifi signal was ok. Used the gym and hot tub, both were fine. Overall a very pleasant experience.
