If you are planning to stay awhile, you might want to contact Bill Wildman who owns a lot of property in Consejo. There are sometimes houses available for rent, though I think they are usually for longer terms than just a few days. try www.consejoshores.com
and definitely go there if you are looking for real estate to buy in that area.
There used to be a really neat little resort there called "Adventure Inn." Too bad it shut down, it was nice, and very reasonably priced, and had a very good restaurant too.
Has anybody re opened Don Quixote Hotel yet, Lan? I hear it changed hands several times but nobody ever re opened it. It looks like it was a lovely place too. I guess its hard to make it in the tourism business up there, but the retiree business is doing very well.
