What a delightful find, Casa Once!! Would stay there again without hesitation. Rosario was lovely and looked after my room, served me breakfast, helped with luggage .. she was helpful in every way. The place is immaculate! In old town Queretaro, where there are so many fine places to dine, listen to music, just wander around … a very walkable town centre. Such a nice surprise after a long haul to get there from Calgary!
