Great hotel, with big rooms, everything is nice and clean. We were particularly impressed by staff, everyone was exceptionally nice and accommodating, we would especially highlight Marin at the restaurant and Nikola at the front desk. Overall great experience and you definitely get what you pay for

The breakfast was excellent and the staff as well. I will remember the staff running to help all the time. Among them Marin was extremely helpful and polite. Beach restorant was terific, sunbeds always prepared, towels as much as it needed, refreshing drinks to the sunbeds, limitless.
I like everything.

★★★★★ A True Gem in Europe
Hotel Milenij in Opatija is simply extraordinary. I’ve been fortunate enough to travel all over the world and stay in many beautiful hotels, but there is something genuinely special about this place.
The location is phenomenal, right on the Adriatic, with the most incredible setting. Waking up, putting on your bathrobe and going straight for a morning swim in the crystal-clear Adriatic waters, then coming back for what is quite simply one of the best hotel breakfasts I have ever experienced, is hard to beat. The breakfast alone deserves a special mention: exceptional quality, variety, presentation and setting. Truly the best of the best. Marin was such an outstanding staff member.
But what makes the Milenij stand out even more is the service. The entire staff is outstanding: warm, elegant, incredibly attentive and genuinely caring. There is a level of hospitality here that is increasingly rare, and it never feels forced. You feel looked after from the moment you arrive.
The sunrises, the sunsets, the terrace, the sea, the atmosphere… everything comes together in a way that feels almost magical.
Hotel Milenij is not simply a beautiful hotel in an incredible location. It has a soul. It is truly something else and, for me, one of those rare gems in Europe that you want to return to again and again.
