Alcùdiamar is a nice sheltered harbour. I’ve spent here 5 nights in January 2020. Although being out of season many bars and restaurants were open (not the ones directly inside the marina). Old town is a short 15 min walk and is pretty awesome as the ancient atmosphere is still felt by walking by the narrow streets and city walls. Showers are good (although super strong chlorine smell in the water), office and marineros are friendly and professional. night fare up to 9mt in january is 14€. Laundry inside the marina is expensive but you leave your basket to the lady and collect it back to your convenience (meaning you don’t waste half a day waiting for it).
