Great place in Athens, as long as you don't mind taking a bus to the metro or city center (which isn't that bad at all).
Note that it is next to the cinema, so occasionally you hear some of the movie next door, but that is always finished by the late evening. Never interrupted my sleep at all!
Very clean and comfortable. Just a note that you will have to top up the internet yourself, but that is very cheap!
If I return to Athens would happily rent again.
