Guest reviews· 8.2/10 (1,038)

Guests generally praise the Mercure Petriolo Siena Terme Spa Hotel for its relaxing atmosphere and value. Many highlight the beautiful Tuscan views as a significant plus, contributing to a "very good experience" for most visitors. The hotel's "great spa facilities" are a consistent draw, offering "thermal relaxation" for those seeking a tranquil escape.

While the overall sentiment is positive, with numerous mentions of "comfortable overnight stays" and the property being a "really chill place," some guests note the hotel's somewhat dated aesthetic. Described as "a Palace from the 80s," this suggests that while the amenities are appreciated, the decor may not be the most modern. Its secluded location, characterized as "in the middle of nowhere," is a double-edged sword, offering quietude but potentially requiring a drive for other attractions.

Additional conveniences like free on-site parking and a coffee house are appreciated. The hotel also offers breakfast in the room, further enhancing the comfortable stay. Overall, the Mercure Petriolo Siena Terme Spa Hotel is recommended for those seeking a relaxing spa retreat with scenic views and good value, provided they are comfortable with a classic, rather than contemporary, style.
