A hidden gem in downtown. A block from el Zocalo and walking distance to several restaurants and historic sites. Other reviews mentioned high noise level. My experience was different. The only noise we could hear was when we had the windows opened; otherwise, it was quiet inside. My personal preference is a soft/fluffy mattress, but the one in our room (Princess) was in the firm side. TV didnt have good screen resolution - blurry.
Overall, I highly recommend Casa Sauto.
