Fly4free hotel review: 5* Six Senses Douro Valley
Although not as well known as other top brands in the hotel industry such as Belmond or Four Seasons, Six Senses is one of the leading players in the eco-luxury segment. Created in 1995, the brand focused on establishing units with unique characteristics, combining a top service, sustainable tourism practices and great respect for the regions where their hotels are located. The Six Senses Douro Valley is no exception to this "mantra".
