Magda and Apostolos were great communicators and did their best to help us, I really appreciated it.
However, the flat is old and tiny (you cannot eat in if you are more than two people, and there is no desk nor a confortable table to work). People who do not know Athens well might need to know that "very centrally located" does not mean that you are in a nice pedestrian neighbourhood 5' away from the Acropolis and the like. Check the city plan to avoid being disappointed!
