We stayed at Nadja's apartment for three nights. It is a very clean, recently renovated, beautiful large two bedrooms/two full bathrooms apartment with a very nice outdoor space. It has everything we needed and more. My son really enjoyed cereal for breakfast ;)
The apartment is very conveniently located - just a few minutes walk from Acropolis museum and the entrance to Acropolis.
We were able to check in early, which was so nice after a long trip from NYC. Thank you Nadja and Bettina! Bettina met us in the morning, showed around and also helped us to arrange a taxi on our last day.
I cannot recommend the apartment enough and we would definitely stay there next time we are in Athens.
