It was very nice, the nicest place we've stayed in all our trips. Our room had three beds, other rooms had one or two, and one room upstairs had five for large groups. Our room (#3) had a "widowmaker" for hot showers, and the other rooms are on a tank that is heated by a natural gas heater, so we all were able to have nice hot showers. Amand, the proprietor, is very welcoming and gracious. The casa has stairs to the roof, where you can go and look out and take photos of the city of Cusco. It is located an easy walking distance from the main square, as well as from two of the Indian markets for shopping. (Actually, the third market was walking distance for us also, but about 1 mile away.)
Amanda serves coffee, tea, and pan (bread) and jam for breakfast whatever time you need to leave, including at 5am, when we needed to catch a train to Machu Picchu. On more "normal" mornings, you also get wonderful tamales made of corn, with some sweetness and raisins in them. Clean towels are provided, as well as toilet paper, something not to be taken for granted in Peru! She also makes the beds for you while you are gone. There is a lovely garden in the courtyard of the casa.
We stayed twice this trip; on the first stay, I left a necklace and earrings in the room. A quick call from the airport and she held them for me and had them waiting for me on the return trip. Ten dollars per person per night is very inexpensive for the level of treatment and service.
