I'll be in Cusco later this month, and I guess I need to figure out where I'm staying. Does anyone have any suggestions for a decent, non-international luxury brand hotel located within reasonable walking distance from the center? (The JW Marriott seems excessive to me - I'd rather find something in the $100-ish range.)

I was looking through a guidebook, and it recommended Tocuyeros Boutique Hotel and another place called Niņos Hotel within that price range. The latter seems particularly interesting, as it supports education for at-risk children in Cusco. Both get good reviews online. Does anyone have any experience with either, or alternative suggestions?

Also, if anyone has thoughts about places to stay in Ollantaytambo and Aguas Calientes, please do share! I have friends that are huge fans of El Albergue in Ollantaytambo, so I'm thinking of spending a couple of nights there before heading to Machu Picchu. And while most people seem to be telling me that Aguas Calientes is pretty skippable, I'm thinking it might make sense to spend a couple of nights there so I don't have to deal with crazy early wakeups to get to my morning MP tour. So any thoughts as to a nice place to stay there would also be most appreciated!
