I stayed here nine days and just loved this rental. One offbeat thing that I really liked was that the dorm-sized refrigerator was outside on the patio. Since this is a very small studio, it'd be a drag to have the refrigerator right in the same room that you'd be stuck hearing switching on and off when you're trying to sleep.
Leonidas is about as kind and professional an AirBNB host as I've encountered, and towards the end of the my stay he even invited me out for a drink with his wife and young son. He gave me some tips that made my stay much more enjoyable. And he was incredibly good about about responding to communication over SMS in a timely way. Check-in was a breeze.
Apart from the amazing view of the Acropolis, this unit is special because it's in a fantastic neighborhood with all sorts of charming restaurants, bars, and places for coffee. I've never been anywhere that had so many nearby cafes with such a good vibe. Several small supermarkets are close by as well. The vegan spaghetti just up the street at Mystic Pizza is one of the best things I've eaten in Europe.
So, yeah, I liked this place a lot. You will too.
