I stayed at Akis's place for a month and can say that the terrace alone made this a great deal. The sun and view are amazing surrounded by plants and greenery. The flat is cozy and has some quirky touches that really give it character. Akis is a very responsive host and answered lots of questions happily. Location is OK but a good 10-15 minute walk from the tube station but this was fine for me. My only criticism is the bed is kind of squeaky and old but nothing major. Overall, a great value option for shorter or longer stays in Athens.
