"Loved it here! The hotel feels very boutique and the area around the hotel is lovely for a walk along the front or a dip in the sea. It's a pleasant 20 mins(ish) walk into Piran along the sea front which is easily do-able but I think there's a shuttle if needed. Wide choice of breakfast and even a robot to help clear tables. We had an issue with parking as there was an event on, but the staff member outside offered us an alternative place to park nearby. Highly recommend!"
