Our review
Overall ratingA
One&Only Portonovi is a newly built luxury resort on Montenegro's Bay of Kotor, highly regarded for its dramatic sea views, spacious rooms, and exceptional Chenot Spa. Guests consistently praise the attentive, personalized service and high-quality dining options, though some note very high on-site prices and minor front-desk process issues.
Best for
- Spa and wellness enthusiasts — The highly rated Chenot Spa and excellent gym facilities offer professional treatments, heated pools, and top-tier fitness equipment.
- Luxury resort vacationers — Travellers seeking a pampered experience will appreciate the immaculate grounds, private sandy beach, multiple pools, and spacious rooms with bay views.
Not ideal for
- Budget-conscious travellers — The resort commands premium pricing for its restaurants, spa treatments, and general services, which some guests found steep.
- Active local explorers — The immediate neighborhood lacks independent shops and restaurants, requiring a drive to reach historic towns like Kotor or Herceg Novi.
Rating breakdown
- ALocation — Offers stunning bay views from the Portonovi resort area, though it is quiet and removed from historic local towns.
- ARooms — Spacious and immaculately clean, featuring large bathrooms, automated curtains, and terraces overlooking the water.
- A-Service — Highly personalized with standout staff, though occasionally held back by front-desk inefficiencies or slow payment-hold processing.
- A-Dining — Excellent breakfasts and high-quality restaurants like Sabia and Tapasake, though prices are high.
- AFacilities — Features a private sandy beach, multiple pools, tennis courts, and the exceptional Chenot Spa.
- B+Value — Delivers a top-tier luxury experience, but the premium pricing across all outlets may feel steep to some.
Verdict
One&Only Portonovi is an exceptional choice for travellers seeking a high-end, self-contained beach and wellness resort in Montenegro. It is less suited for those on a budget or visitors who prefer stepping directly out of their hotel into a bustling, historic local town.
