★★★★★ 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.

A very good design of hotel, great staff and hospitality. Very good swimming pool area and 30m to walk to sea side as option. Breakfast was great with caviar and prosecco))

We are extremely satisfied with our stay at this hotel.
From the moment we arrived, we felt very well taken care of. The staff were incredibly friendly and always willing to help. The food was delicious, and the breakfast was of an exceptionally high standard with a great selection of fresh products.
The spa area was wonderful, and we truly enjoyed the time we spent there. The rooms were beautiful, spotless, and very comfortable. The bed was excellent, and the view from the balcony was absolutely breathtaking.
Everything was maintained at a very high standard. This is definitely a place we will return to in the future. We highly recommend it and can honestly say that we are 100% satisfied with our stay.
