Positives: The apartment is absolutely stunning and spacious. It was very clean and Andreas was very welcoming and provided us with useful tips about Athens.
Negatives: every night of the stay there was a heavy metal concert on the square next to the flat which made it impossible to be in the flat between the hours of 7:30pm and 12pm. On top off that the last two nights there were riots on the streets and the police used teargas which made it impossible to open the windows. If we knew that there would have been a concert we would have not booked the place. I recommend you check with Andreas before booking!
