Beautiful hotel, the grounds are well manicured, lots of flowers and trees. The view of the mountains around the valley is wonderful from the balcony of the hotel room. The people that work the front desk are very nice, and most speak several languages--including English. One night we got back very late from our trip to Machu Picchu and my voice was raspy, the clerk at the front desk insisted I follow him to the kitchen, where he made me a pot of tea and carried it to my room for me. Super nice guy.
One small piece of advice: if it is autumn or winter (in South America) while you're there, ask for a heater at the front desk when you check in. We did not and our first night there, we were miserably cold in our room. We requested a heater, and they gave us a portable space heater to use at night--it made a big difference.
Another tip: From the hotel, walk straight down Jr. Grau to Plaza de Armas--find the lady that is making picarones out of a cart around the square--picarones are like doughnuts, with a honey glaze. She sells 3 picarones for 1 soles and they're the best we had while in Peru.
