Is there a rocky beach across from hotel & can you swim there? How far is to a sandy beach & is there a bus?
Apologies as I haven't logged into this account for a while. The beach across from the hotel is not suitable for swimming but if you cycle you can hire a bike or scooter and it's a nice scenic cycle along cycle lane to the beaches. Two nice beaches I visited were di Maria Pia and Bombarde. Public transport is not the greatest in this location. Hope this is helpful.
There's a tiny bay just across the road. Unsure of any other beach. The pool area is excellent and sea water.
