Panagiota's flat is perfectly located, close to everything you will visit in Athens. The rooftop is as amazing as you see on pictures. But the flat itself could be very disappointing because you live actually in a shop! So to leave, you have to open and close the big padlock of the shop, which is not very convenient and the first floor where the bedrooms are is a thoroughfare. Even the rooftop is opened to strangers...
You have to share the bathroom/toilets with all the bedrooms, so be ready for that too. And to finish, you have also to know that coffee is not free! For sure it's the first time I have to pay 1 euro (it's the same price than in a real coffee shop!) to have a coffee in a Airbnb! I don't recommend this flat.
