As we arrived late into Athens Marika arranged for a taxi to pick us up from the airport and for the driver to give us the keys to the apartment.
We found our way around the flat easily; it is on the roof of an office building, so there was a friendly concierge during work hours to ask any questions we had. The view that you can see in the pictures wasn't a let down! The apartment is modern and compact with everything a hotel room would have (but more charm, privacy and an unbeatable view).
The location is perfect for exploring everything the city has to offer. It is a very short walk to the Acropolis and Ancient Agora. There are a host of restaurants on the streets nearby and lots of cafes and bars in nearby Plaka and Psyri.
Overall, we had a wonderful stay and had no problems (aside from patchy wifi). We would recommend for the view alone, and would love to stay again!
