Just book it! You won’t regret staying at Nada’s place.
The flat is about 10-15 minutes away from the metro, which includes walking to the metro and getting to the centre. The flat was compact but had everything you needed during your stay, and the view of the Acropolis was absolutely stunning. You have a huge balcony completed with sun beds and chairs. Definitely worth getting up early for the sunrise and a cool drink for the sunset.
As for the host, Nada was very friendly and stayed in contact throughout the stay. Definitely coming back here again :)
