We loved our stay at the grand Hotel. Hotel staff were especially kind and helpful, and especially Christoph and his colleagues, who went above and beyond to help out with some special requests. For a family of four the suite 301-302 was perfect! Two separate rooms in the same suite, one with a terrific sea view, and the other with a partial sea view. With kids, the casino was not of interest, but the hotel is perfectly situated on the boardwalk of an idyllic little beach town. You can reach the beautiful pink granite coast via a 30- 45-minute walk from the hotel along a wonderful coastal trail.

The hotel was lovely and tucked away in Trebeurden. Very quiet and sea views from our room, absolutely stunning! The room was spotlessly clean and lovely ensuite. We had a patio with sun loungers with our own little garden. Our room included breakfast which was slightly disappointing as a few basic problems which could have been avoided. The egg boiler didn’t have enough water in it so asked for a refill but it was filled with cold water and never boiled while we were at breakfast! So no boiled eggs ! The croissant were undercooked so not flaky and the coffee was warm . All avoidable, so frustrating and spoiled our breakfast. The staff were very helpful but frustrating for us !
