The verdict
La Querce takes the lead
La Querce scores 8,1/10, ahead of Argentario Lagoon Resort & Spa (7,4) et Isolotto Guest House (7,1). A hotel of nine Junior Suites set in a renovated 1930s inn, at the entrance to the old village of San Casciano dei Bagni, 1 km from the Fonteverde thermal centre. Pool and parking are not specified; the great Tuscan sites are 15-40 minutes away by car.
Choose Argentario Lagoon Resort & Spa if…
