You absolutely cannot beat the views from Alexia's penthouse suite. Truly spectacular views of the Acropolis night and day. Extremely well located to the Metro as well. We took the Metro to and from the airport and the port of Pireaus. We also took it to and from the Acropolis although we could have walked.
Alexia is an excellent host. Very communicative and helpful.
This is now my go to place in Athens.
