Corinna's loft is just perfect. It is spacious, tastefully newly decorated and equipped at the level of a 4 star design hotel -- also important: it was clean (actually, it was spotless). And it is in a great location. We could easily walk to bars, museums, the acropolis, the plaka, the fish, meat and vegetable markets, shops, restaurants, etc. And it is right on the metro line that runs to the airport.
I could not imagine a better place to stay in Athens and we will definitely be back.
