Aguas Calientes is a small town, and really only has one road that the bus travels on, and this hotel is one of the ones that are Right next to the street. HOWEVER, there was barely Any noise in our room (which was directly next to the road with a mountain view) and we had no trouble during the night.
The staff were amazing and very helpful, and they even offer you a free delicious alcoholic (or non, if you prefer) to enjoy at any time during your stay.
The rooms and the bathrooms were very clean, and everything was just lovely. The only issue, which is not at all limited to this hotel, are the mosquitos (or other bugs) that will bite you relentlessly! So make sure you bring bug-resistant spray or something, and do not open hotel windows (as recommended by the staff as well).
