Miltos' place is really awesome, even better than the pictures; he's an amazing host too, gave us advice on sightseeing and how to get around. It was spotless clean, very quite despite being in the center of Athens. The location couldn't be better, we walked everywhere. The wi-fi was really great, I had to work during my stay and there were no issues with the connection. Also at the entrance of the building there's a Gelateria where the ice creams are incredible. If I ever return to Athens I'd definitely stay there again!
