We stayed at Los Cuatro Vientos in 2001. On the plus side, it is cute and the rooftop bar is a wonderful spot for a late afternoon cocktail.
We found the staff quite pleasant, as well. The drawbacks: Our two-room suite was dingy and dark and smelled of mold and sewage. This was definitely the hotel's worst room and we had no warning when we booked even though we booked directly through the hotel. The place is small, so when we asked to switch to two smaller rooms, none were available.
We definitely got the impression the owner is trying to squeeze every last peso out of the business. Breakfasts were awful by Mexican standards. The fruit selection was poor and fresh juice was offered only 2 of the 7 days we were there. Similarly, though there was a wonderful bakery right down the street, the more typical fare offered at the hotel was sliced white bread from a supermarket.More
