Everything was great, the location is great, 1 min walk to Syntagma square. Very easy to get to apartment from airport by taking Metro. Apartment has everything you need for stay. It corresponds to pictures and it was clean and ready when we entered. There are couple of small things for improvements: balcony door is wooden old door that doesn't close well, and that was making me worry to leave important things in apartment when we were going out. The apartment is heated by air conditioner and one day we were cold but it was our first day when we arrived and it could be that we were not fully aclimated to new weather for us, all other days were ok. The door of the main building sometimes was being closed and it was quite hard to open with the provided key.
Overall I have enjoyed my stay with my family and this apartment satisfied all our needs!
