The apartment is great you have the privacy of your own room and have the opportunity to meet new friends from other guests staying at the apartment.
With a full kitchen or many restaurant walking distances it suits anyone desire of how to travel; metro, trolley and bus stop are just outside the place.
If you are planning to do the Athens marathons the shuttle busses pick up is right across de street.
The attention that I received from vaki and mike was above and beyond (I had more interaction with them than with a concierge at a hotel). Definitely a must for either one room or the whole place if traveling with family!
