Perfect flat. The view is incredible and the rooftop is great to hang out. The flat is spacious enough and has everything you may need as a traveler and it is easy to prepare meals there. As for the location, I really don't think you can do any better in Athens- we were right in the centre of Plaka which is the most beautiful area- the architecture, the amount of bars and resturants and the little streets with lots of history. Also, it took us less than 10 mins hrough the beautiful streets) to get to Acropol. Best place to stay in Athens and a great value
