I have stayed in a number of converted haciendas in the Yucatan over the years, some more pricey than Hacienda San Francisco and some less. Hacienda San Francisco compares well to these others, and I recommend it.
Overall, the hacienda is very charming. When staying at a hacienda, we expect an odd pull between comfort with some nice, high-quality details and a bit of a rustic nature. That's what we are looking for, and that's what we found here.
The accommodations were comfortable, clean, and spacious. The beds, bedding, and towels were of a high quality, and the bathrooms were well-appointed. Our room had a back porch with a kitchen space (including refrigerator) and a plunge pool. Not all rooms are air conditioned, so if this is a concern, you should confirm that yours is. We had one room with AC and one without, which worked well for us, since some in my family want AC and others prefer warmth and complain about cold ACs.
The staff was very warm and hospitable and seemed to keep things running well.
While at the hacienda, my sons enjoyed horseback riding and a great pottery class. They also played on the basketball court, and we all enjoyed taking walks and playing games in the small rec center (pool, table tennis, board games, etc.).
We ate several meals at the hacienda's restaurant. The food was great, and the waiter and chef were very nice. (Here deep in Mexico, my sons had the best french fries I have tasted.)
