With Asteris place you have a full apartment at your disposal, located at a nice and pretty central area of Athens. Maybe even better is your flatmate Asteris himself, who is a very welcoming, funny, friendly and helpful guy! His responses to our emails were always super quick and helpful. Couldn't have been better.
The apartment is is very well organized and there are some clever little gimmicks that Asteris will show you, that will make very good use of the space available. If you need food late in the evening, I recomend you to go to one of the kiosks nearby; Asteris might have a better recommendation for you, just ask him :)
The apartment has a small balcony that's excellent in case you're a smoker or if you just want to have a coffee outside. Coffee machine and coffee is available!
For me there are two things that are important for a place to stay: It should be clean and it should have the essentials that you might not want to carry around with you for every flight, such as soap or towels. This was definitely a given. You'll have everything you need plus an awesome host. I am pretty sure that you won't regret the stay - on the contrary.
