We had an amazing stay at Valamar President. The staff was extremely accommodating and nice, and was very helpful whenever we had any questions or requests. The breakfast was particularly nice, with everything you could wish for. Especially the garden-fresh honey straight from the bee hive was something I have never had before, and I highly recommend trying it.
The beach is right outside the hotel and has a beach bistro with very nice food, although the drinks there were 'only' okay. The beach is not really suitable for small children as it is pebbly and hurts a bit to walk on, but for adults it's a nice and private beach. You should rent sunbeds if you plan on staying on the beach for the day, but the price is reasonable, especially if you are a guest at the hotel (half price off of normal price).
We went just before the high season started (ca. mid-June), and this was perfect. The weather was nice, not too hot, and the beach and restaurants were not crowded.
All the rooms at Valamar President have an amazing ocean view of the Adriatic as well as a lovely, large terrace with sunbeds and chairs.
We have already decided to come back next year. We fell in love both with the city and with the hotel.
