Free wifi available all over the hotel. Please note that it has a limited capacity. For faster wifi, we can send a budget. The Hotel celebrated 20 years and we wanted to mark this date with an important renovation of our Hotel that allows us to project the next 20 years of the future Onyria Quinta da Marinha Hotel, we can say that our rooms are entirely new, only the remarkable balcony views survived, a brand new bathroom gained space and versatility, in the room with the option made in the furniture we were able to deliver more space available to the customer, reinforcing all the amenities of a 5 star room with the technological characteristics of today. In this Renovation we wanted to bring an inspiring setting to the rooms, in order to increase the relationship and dialogue with nature that surrounds the hotel and the golf course. Harmonious choices and high-quality materials make each room a warm and welcoming area. Our guests will see the predominant colors of the natural park in the room, but they will also feel a greater sense of comfort, space and design. In the rooms there is a very large piece by the visual artist and illustrator, Kruella D’Enfer
