Aguas Calientes is an amazingly well organized town. Its main justification for existence is to facilitate the visit of tourists to the ruins at Machu Picchu!  and it does this brilliantly and efficiently.  The Casa del Sol hotel is close to the railway station: indeed the tracks run along the street right in front of it, which is reminiscent of Indian hill towns. The buses for the ruins run from just 50 yards away, so it is a very convenient place to stay if you are visiting the ruins! and why else would you be in Aguas Calientes?  The staff were very helpful and our room on the fourth floor was good, with a view out over the river behind.  Breakfast was fine and the wifi was good.  The staff were perhaps the most helpful that we had encountered so far on our trip to Peru. They really did go the extra mile to assist us.  Great place to stay.  

Beautiful hotel, good food and service, perfect for the Machu Pichu.

lovely meal and lovely service. Train going past the hotel door can be a little noisy and disconcerting.

"This new and modern hotel is conveniently located for the railway station and the Machu Picchu bus stop as well as all the principal offerings of the town. Service was excellent and the hotel is clearly striving for an up-market offering. My room was lovely with views over the river behind the hotel. The hotel's aspirations were reflected in a dinner menu that aspired to fine dining but didn't quite pull it off. The result was a rather restricted choice within a limited set menu. Breakfast was, however, excellent."

"Casa del Sol is a great choice location wise and for overall service provided. All rooms have a fantastic river view. The provided dinner was excellent."

“Casa del Sol - also very good - kindly let us use facilities on last afternoon, after we had checked out, so we could shower before we got train back to Cusco.”
