Very nice appartement, super clean, with all facilities and a nice balcony where we could find shadow whatever the hour of the day simply by moving the table and the chairs. We loved Pserimos and from 11:00 to 17:00, when all the pirates boats are here and the main beach is crowded, you can go in ~40mn to very nice, remote and quiet beaches: Vathy and Grafiotisa. We stayed 6 nights, we would have liked to stay longer.
Last but not least, Nomiki is very responsive person, who even helped us to find a cheap alternative room in Kalymnos as the boat from Kos to Pserimos was cancelled due to bad weather.
