In reply to HB1: Ah sorry thought you had know knowledge of the island.. last taxi I paid for was 25e but that was early hours of the morning I have only heard of 18e being charged.
Bus time tables are an estimate at best, In my experience I would give 10-15 mins either side of the time stated..but there will be one if you wait long enough..2-3e I think, but I don't use them much so I could be wrong.
