Booker beware. If you want to play golf then this hotel is fine but if you want to use the indoor pool there’s a charge, a bottle of water in your room is chargeable. Breakfast is more like the quality of a holiday inn express. They even ran out of butter and parts of the breakfast menu are chargeable even when it says included 🤷♂️. Our hotel experience was not good. Very limited menu The hotel’s starting feel tired with loose and broken decking boards, cheap fixes etc. the hotel is in an isolated location with nothing really in walking distance. sadly not the standard we expect from a 5 star hotel. It’s only saving grace are its staff who try their best the keep Guests happy.

We had a wonderful time—the premises are lovely, the staff is exceptionally attentive, friendly and efficient. We were a large family group here in vacation together. The staff covered every detail to make our stay comfortable—old and young alike with tact and consideration.

The hotel is located near the central attraction in Cascais, and the hotel offers free transportation according to tid policies. The golf course is right nearby. The staff are very nice, helpful and friendly. It is a great hotel, and the Golf Villas can be recommanded. With free golf and delicious food, the price was resonable.

From start to finish, my stay at this hotel was absolutely perfect. The entire experience exceeded expectations in every way. The hotel itself is exceptional — elegant, comfortable, and impeccably maintained. The rooms are spotless, with great attention to detail in both cleanliness and comfort. What truly makes this hotel stand out is its wonderful staff. Everyone was efficient, friendly, and always ready to help with a smile. A special mention goes to Kátia and Louise, whose kindness and professionalism made my stay even more enjoyable. The restaurant is also outstanding, offering excellent food and service that match the hotel’s high standards. This is truly a reference hotel — one that sets the bar for quality and hospitality. I can’t recommend it highly enough and look forward to returning soon!
