We really really enjoyed our time in Naoussa and liked the apartment a lot.
The apartment was bigger than we expected (two rooms and two bathrooms, two balconies). It has a very well equipped kitchen.
The location was just as perfect for the four of us. I would say more central in Naoussa isn't possible. I have to mention though that it was very loud especially at night. We liked the buzz and being surrounded by party but I wouldn't recommend the place when you want a calm stay.
Last but not least I want to mention the nice hosts. We were picked up by the port for free and they always answered very quickly.
We would definitely like to come back next year.
