Nikos was unbelievably helpful and friendly. 4 of us stayed in a 1 bedroom that sleep 4, 1 queen In the br, and two twins in the living room. The place is very clean and there are a bunch of amenities such as pool, billiards, bar, balcony, Fusball, dogs. It's not in the heart of the action of kos but it's walkable and there are markets, restaurants, beaches, and vehicle rentals all within just a 3 minute walk. Very affordable too!
The only real con was that the wireless internet was very shaky/poor and most of the time wasn't accessible from our room but the restaurants nearby have very good signal.
I will stay here again next time I'm in Kos!
