It is a beautiful place, especially in the evening. There is an expensive marina with big yachts to give you ideas on how you can spend huge amounts of money, an open air cinema to watch movies under the stars and many cafés, bars and shops, restaurants. My favorite place is Mare Marina where you can have a drink and enjoy the view below. Even if you own a car is better to get there by taxi or tram (stop trocadero). It is about 10 km away from the Athens city centre.
