Perfect in every way.
We arrived late at night but the instructions to gain entrance worked well. Astikon Studios are conveniently close to Syntagma Square and across the road from The National Gardens. They are on the edge of Plaka and a short walk from the Acropolis and the Ermou shopping area. Monastraki and Lycabatus Hill are easily walkable too. They are perfectly situated for public transport to the airport by train/bus and seaside by tram.
The studios were spotlessly clean and tastefully decorated. The sofa bed was of good quality and the shower was amazing, it was both hot and powerful and did not flood.
Thank you to the lovely Irini. She was very helpful and nothing was too much trouble.
