We had a wonderful stay at Thomas' appartment. the location is great, very close to all the attractions (you can walk to nearly everywhere, to the Akropolis it is only 15 to 20 minutes). One of our highlights was dining on the beautiful balcony with a view of the Akropolis.
The room was as depicted, very cozy and modern, and enough space. If we travel to Athens again, we would definitely stay in the same flat 🙂
