We've spent a great week at Ioannis' place in Kalamaria. Very nice flat and well equipped, all the amenities are working great, which helped a lot since we stayed with kids. There is a parking slot available (which is not at an obvious place at the first glance - don't forget to download or print out Airbnb's picture to not get confused). Ioannis helped us with everything needed and even left some bottles of cold water for us - also he helped to discover the area and find some interesting restaurants and other places. Totally recommended!
