Reviews
“Beautiful Property Focused on Providing Guest Services”
We were greeted at the entrance when we arrived by Nono who is not only willing to help, but wanting to help. We were escorted to our room and any place else we needed to go on property. Luíza, the reception manager, exemplifies what it means to provide guest services and genuinely cares about the guest experience. Mariana at reception was always pleasant, smiling and available for any concerns. All servers, whether at the bar, at breakfast or at the restaurant provided professional, friendly service. Food quality was excellent and the ambience is fabulous. The entire property offers a relaxing, calming experience. We did not take advantage of spa services but did find the pool, sauna and steam room rejuvenating and beautifully maintained. We were at the property for a one night stay previously and wanted to return. On this past 3 night stay we left wanting more time and definitely will return.

“A wonderful experience – we will definitely be back!”
We spent a few days at Onyria Marinha Cascais as a couple, hoping to relax and enjoy some quality time together, and the experience exceeded our expectations. From the moment we arrived, we were warmly welcomed by Luisa, who made us feel truly at home. We absolutely loved the breakfast, the peaceful atmosphere and the beautiful views over the gardens. The spa was also one of the highlights of our stay. Maria welcomed us with such warmth and kindness and helped us choose the perfect treatment. We also had a wonderful massage with Andrea and Daniela, who went above and beyond to make sure we felt comfortable, relaxed and well looked after. It was exactly what we needed: a chance to switch off from everyday life, unwind and enjoy some special moments together. A big thank you to the entire team for making our stay so enjoyable. We left feeling refreshed and already looking forward to coming back! Highly recommended!

“The perfect getaway in Cascais”
Onyria is fantastic. The general manager, Diogo, is a superstar and very much of a wine buff. Great location, quiet, peaceful, great for golfers and families alike. Good food, great service, large and spacious rooms. Good parking. We are definitely coming back. Thank you!
