The Municipal Information Office (tel. 28410/22-357; firstname.lastname@example.org) is one of the most helpful in all of Greece, perhaps because it's staffed by young seasonal employees who have some energy and enthusiasm to them (mid-Apr to Oct daily 8am-10pm). In addition to providing maps and brochures, it can help arrange accommodations and excursions. (To the left, just around the corner, is a small Folklore Museum, open usually 10am-6pm; admission 3€.) Of several travel agencies in town, I recommend Nostos Tours, 30 R. Koundourou, along the right arm of the harbor (tel. 28410/26-383).
