My girlfriend and me had a very pleasant stay at Helens pension. Our host was friendly and courteous and gave us good tipps on restaurants etc.. A driver even picked us up at the port at the arrival. The room was rather spartaneous but all clean and appropriate to the price. The village of Karterados is a bit offside touristic Fira. We would recommend a vehicle anyways because the charme of the Island will not be present in Fira but more offside the touristic tracks. Thank you Helen for the great time we could spent on Santorini!
