Really enjoyed staying at Asiri Cascada del Inka.  It was a brand new hotel, really comfortable, very clean, hot showers.  The beds were great, the breakfast was delicious, with fresh breads, fruits, juices, coffee, teas, yogurt, and cheese/ham.  It was a little far from the center of Cuzco, but it was a nice walk through San Blas (great neighborhood!) and very safe, and I'd choose a less expensive nice hotel over being in the center of everything.  The staff was very friendly, although most only speak Spanish which could be a concern for some people, but I enjoyed as it was fun to practice my Spanish.  A few staff members spoke English through.  Overall great, comfortable stay.
