Four adults (with 1 x duffle & 1 x backpack ea) will be needing to get from Athens to Rafina, for our ferry to Andros the following morning. We plan to get to Rafina late afternoon, early evening. Is it simple and straightforward to travel on buses or trains or is it better to pay more and go with a taxi? If taxi, which company is recommended? I have read a few posts on Uber, so I won't bother to ask THAT question - I'm assuming it is still not accepted practice in Greece.
