I was traveling around Greece alone for 2 weeks and Toni's apartment was definitely my favorite! The location was great because it was right across the omonia metro station, which is just 1-2 stops away from the Acropolis, Syntagma and Monasteraki.
The apartment itself was huge for one person, which I didn't mind because it still felt homey. The bed was very comfortable, the place was clean and and the amenities (toiletries, coffee, tea) even beat other hotels!
I absolutely enjoyed my stay at the apartment and would definitely recommend this to friends and other travelers :)
