We are staying in an apartment close to Hotel Floridiana, I have heard that the Sita buses are sometimes over crowded and do not pick up very often at Praiano. I have also read about a local bus which goes up and down the hill from Praiano to Positano. Can anyone provide further information on the subject, have checked other postings but not really answering my question. We will be there in May if that makes any difference. Thank you for any advice.
