This was our 2nd stay at this place : we had booked another accommodation but we had been so satisfied with our stay at K2 that we changed our plans ! Location is really convenient : close to the city center and monuments ( walking distance), close to Piraeus Port ( only few metro stations), very good restaurants in the area ( Melina shared recommendations we really enjoyed ). The design of the flat is lovely, wifi connection worked very well . We enjoyed our stay and will come back again !
