Very nice apartments, great location just off the main centre and close to the beach. Had a great time.
Nysiros is a beautiful island. Don't go on the trip with reps. Theres a guy (from Nysiros) in the harbour at Kardamena with his own boat "Konstantianoz", go on the "special tour" on Thursday. This takes you to Mandraki where you are met by an English guide (Mike) that lives on the island, he walks you around Mandraki and then by coach to two of the mountain villages and on to the Volcano. The trip continues on to another harbour and beach at Pallis where you catch the boat back to Kardamena. Its a great, full day out. Costs 30 Euros that includes the boat, guide and the coach.
We went 17th-25th May 2003, great weather, got burnt. 1 day was a little overcast but went to Nysiros that was baking hot all day.
