Second year in a row I've been staying with Lupe and her son for more than just a few days. She's still as cool as ever, and just about the most accommodating host you can imagine.
For more details on the place, see my review from last year. The only major thing that's changed is that there is now air conditioning, so that's probably a big bonus for many.
You probably won't find a better, more central place to stay at for this price, plus if you have a chance to get to know Lupe better, you'll find her to be a wonderful and interesting person with a lot of surprises in store.
