Mikrolimano is the harbor area in Piraeus, a short distance away from Athens, Greece. The harbor has plenty of fishing boats and a yacht marina with luxury yachts and smaller pleasure boats, and the area is surrounded by cafes and restaurants. The atmosphere feels a bit like being on one of the islands while still being just a few minutes outside of Athens. Many Greek films have used Mikrolimano due to its beauty and atmosphere.
Some people come for the charming harbor itself, but most people come to splurge on a nice seafood dinner or lunch at one of the high end restaurants. The seafood here is not cheap, and it is usually sold by the kilogram, so keep in mind that 1 kilogram equals about 2.2 pounds. If fish isn't your thing, you can still come here for the views and the experience and order steak, grilled meat, or a number of other local dishes.
Mikrolimano is located in Piraeus, about five miles from the Acropolis in Athens. To get there, take the metro to Piraeus and then the #20 trolley to Mikrolimano and go down the set of stairs until you reach the harbor.
