Top Slovenia Adriatic Coast Hotel Reviews

Barbara Piran Beach hotel

10/10 Excellent

"My partner and I stayed for one night at Barbara Beach Hotel and enjoyed our stay. The room had an amazing sea view and was spotless throughout. The breakfast had a range of hot and cold options so there was enough there to choose from. We had access to the loungers as part of our stay so utilised these in the afternoon, there were plenty available. The steps down to the sea were quite slippery and could do with upgraded safety as many guests struggled getting in and out of the water. The location is perfect for enjoying a peaceful break but with easy access to Piran with a 15 min walk to the town centre. All in all a great stay."

Hotel Histrion - Sava Hotels & Resorts

10/10 Excellent

"We had a lovely stay at Hotel Histrion. Our room was clean and comfortable, and it was great to have a kettle and mini fridge provided. The only downside was that the tea and coffee weren’t restocked during our stay. Breakfast was fine, with enough choice to start the day. A high chair was also always available for our daughter, which was really convenient. Unfortunately, the indoor pool at Hotel Histrion was closed during our stay, but this didn’t matter at all as we had plenty of other options. We were able to use the outdoor swimming area at Bernardin Plaza, as well as the outdoor pool at Apartments Vila Barka, free of charge. We also had the option of using the indoor pool at Grand Hotel Bernardin, but the weather was so lovely that we much preferred being outside! The outdoor swimming area at Bernardin Plaza was fantastic and really made our stay. It was a great alternative to the closed pool and meant we could still enjoy plenty of swimming and relaxing in the sunshine! Overall, we had a very enjoyable stay and would happily return!"
