The matter is simple. A nice dream.. to visit Greece amid political unrest, as said one commentator booking.com .. No problem .. Search hotel outside the city center on the basis of good reviews .. Greek reception, professional information, friendly atmosphere, genuine interest for the ephemeral small needs for the guests created out of nothing in a foreign land .. and then hear to the local storytelling in in a very historic place..
Our British friends and Mexican as well who flew to Athens for a few days..  so simple.. they enjoyed a cruise of one day. . We found the opportunity to reiterate information we found here and there .. and then to go to the source one day and describe things with our own pen!
Lets go then with http://www.olympiccruises.gr/ to Hydra, Poros, Aegina!
 
A visit to the Historical Archive Museum Hydra is an exciting journey in history. The museum houses important paintings from the 1821 century and war. Among others the following do stand out:  The Great Harta by Rigas Feraios, crafted by the great Greek visionary, printed in Vienna in 1793 and the silver jar with the embalmed heart of Admiral Andreas Miaoulis. Visitors can also admire a very significant contribution of personal mementos by the by the glorious winner of the Balkan wars, Admiral Pavlos Kountouriotis.
At the shop you can buy replicas of museum copies, signed serigraphs of works by famous painters (Greek and foreign) that have exhibited their works in the museum and special editions for Hydra and Art in general.
