Nasos' apartment was perfect for our two nights in Athens. It was in a brilliant spot close to all the main sights and with plenty of great bars, restaurants etc just a short walk away. It was only a few minutes walk from the Monastiraki metro too, with connections directly to the airport or harbour.
The apartment is small and simple, but still had plenty of room for the two of us as we were out and about for most of the time.
You couldn't ask for anything more from an Airbnb host either. Check-in was super convenient and we had good communication before and during our stay. Nasos gave great recommendations on local things to do and places to eat and drink at. He also has a small number of discounts available for particular places.
We would highly recommend staying here.
