We had a great stay at Panos' apartment! Everything worked very well, both Panos and his father were very kind and helpful. They even left breakfast for us which we enjoyed a lot. In our opinion this is the perfect spot to visit Athens, close to the center but at the same time calm enough to have a good sleep. The flat is large and clean, and the big balcony is a really relaxing place where you have sun even in November from the morning on. We can only recommend this place to other travelers.
