One&Only Portonovi5

Overall impression: One&Only Portonovi presents as a high‑end resort on the Bay of Kotor with striking sea views, spacious well‑designed rooms and a large Chenot spa. Reviewers consistently praise immaculate grounds, large bathrooms, terraces overlooking the bay and highly attentive staff — many guests name employees (Petar, Julieta, Jimmy, Sagar, Milica) for outstanding service. A minority of reviews report procedural issues such as large card holds or front‑desk confusion and several guests comment on high on‑site prices.

High‑quality rooms & maintenance: Rooms win praise for cleanliness, spacious bathrooms, automated curtains and terraces with bay views.

Location & transport

Location: Set in the Portonovi resort area on the Bay of Kotor. The property’s main asset is the bay view; the resort area itself remains quieter and less 'lived‑in' than nearby old towns.

Nearby highlights: Tivat Airport ~6.9 miles; Kotor and Herceg‑Novi reachable by short drives for sightseeing.

Transport: Guests rely on taxis or rental cars; the hotel offers transfer and paid yacht services mentioned in reviews.

Walkability: Extensive resort grounds are easy to walk, but the immediate neighborhood lacks many independent restaurants or shops.
