Thanks for a great time in your fantastic apartment, Alexandros!
A very stylish, super-clean place high up in the building (with elevator), amazing terrace, air condition, good internet connection and high quality furniture and equipment.
Check-in and all communication throughout have been nice and very fast.
The area just outside the building has been converted into a pedestrian area with many trees, fountains and restaurants, which I liked a lot. The closest metro station is maybe 15 minutes walk away, but busses are closer and taxis (bookable through Uber) are cheap compared to other cities.
Thanks for being a great host and the great time in Athens!
