8/10 Very Good! (742 reviews)
"Great hotel right on the seafront. The staff are very friendly and welcoming. The rooms are spacious, cozy, and very clean. Breakfasts are good, which is a big plus. During our stay it was seaweed season, and the smell was quite strong, but it wasn’t a major problem."
