Ios is also part of the Cyclade islands in Greece. It’s more of a party island. We stayed at Princess Sissy Hostel. Pretty central location, you could walk to the port, beach, or the bars and restaurants. We got there on the 4th of July and took a bus to Far Out Village. Far Out Village is a party hostel right on the water. It has a pool and a couple different bars and always has a party during the day and night, perfect for the 4th.
The next day we went to hotel Petradi with a pool over looking the beach at Far Out Village. It had such pretty views.
