First of all, great location. All the main places are quite near and easily accessible by the metro which is literally 30sec from the apartment. Eg, to go to acropolis, only one change is reqd, Piraeus the main ferry port is on the same green line, so good line to be on.
Second, very nice house with great amenities incl Netflix, and games like chess.
Third and most important, superb hospitality by Aris, who was always available. He gave us useful local tips and provided stuff we required additionally like ironing board, clothes hanger, attended to wifi issues promptly, and made us comfortable. The kitchen was also well equipped.
Overall great place to stay and my kids enjoyed a lot. So highly recommend.
