We enjoyed a relaxing 3-night stay at Les Costans this April. We had a superb sea view from our room and access to a small table and chairs and deckchairs on the terrace. The hotel is small and friendly, with a personal service. The continental breakfast was a good spread, with delicious fresh orange juice and hot chocolate.
Our shower room was a little tired and would benefit from a re-fresh, if not a whole refurb, and there aren't many local restaurants open for dinner (at this time of year, at least). If you have a car it is quick to drive to the beach or marina area for dinner, otherwise a 15-minute walk.
Superb access to the walks along the beautiful Granite Rose coast and excellent boat trips to the islands to see puffins etc..
