We only had 2 nights in Athens and wanted to spent a full day visiting the Acropolis and the Acropolis Museum. Loannis' place was perfect for us. It was an easy walk to the Acropolis and the museum is next to the Acropolis. We had a full day there and then walked to the nearby Plaka for a meal.
The apartment was much larger than expected. Super clean and modern feeling. Having a kitchen was a big plus. It was big and fully equipped. We cooked breakfast in the apartment both mornings.
