Exactly what we were looking for!
We spent one week there and enjoyed every moment. We had a large family apartment with 2 rooms and a balcony. The kitchenette was well equipped, so we sometimes prepared our lunch and ate on the balcony, which was very nice. The pool has sunbeds and a view over the sea. The beach is very close, so you can chose between swimming in the waves or in the still water of the pool. The location is really ideal, since it's a quite neighborhood but still very close (10 min walk) to the restaurants, bars and shops of charming Naoussa. The staff is really friendly and helpful. They speak English and German.
