Was led to believe Miguel and Ana Doris spoke English; which was important to us, since we wanted to talk to everyday Cubans. We hardly saw Miguel, and his wife spoke about as much English as I spoke Spanish...which is not much. Yet, Ana Doris was a charming host, and the people who lived there (or were just staying there--we really couldn't tell, it is such a big place) were very congenial. The language barrier was a bit awkward and frustrating, though. We would have like to pick our hosts' brains for tourist recommendations.
The A/C went kaput in our tiny upstairs room. Thankfully, we did have a fan and it wasn't too warm. Our room faced the street and it was not uncommon for folks to be yelling outside after midnight. I would not recommend that particular room if you are a light sleeper.
Across the street is a small bakery/bar where you can buy bread and a cold beer if you so desire. The Casa is pretty cool architecturally, and it is fairly close to Old Havana. All in all---kind of a mixed bag---probably better if you speak Spanish. In any event--i wouldn't be afraid to stay here again. Good breakfast!
