We (Frans and Martine) stayed in Bihan Ti Glas for a week end of August 2019. We had a very nice stay in a lovely 'maison en pierre' in St Quay Perros, a small village close to Perros-Guirec, a bigger seaside village. It's a charming house with two beautiful outside terraces, big garden and one very comfortable bed room with an adjacent small bath room. The advert says it is for 1-5 persons, I would advertise this house any time for a couple or a family with (smaller) children. For two couples I would say this is not ideal because there is only one bedroom and one small bathroom. However, Margot, the very friendly host, has more accommodations in this area which are highly recommendable.
