The perfect apartment if your intention is to stay there mostly at night : excellent location in Biarritz, very stylish interior design, high quality beds and kitchen, high level of cleanliness.
Not ideally suited for staying indoors during the day: limited 'living space' (small couch) and no view or outside access (windows not visually accessible) - but this should not be a problem, you are in Biarritz after all: go outside!
