Konstantinos' place was not unlike a hotel room with a large balcony. The location - which I was not completely enthusiastic about before making the trip - turned out to be the perfect choice. We loved the summer vibrancy below while the apartment was cozy above.
Lots of restaurants and shopping all around and easy walks to anywhere we wanted to reach in Athens.
We didn't stay very long so the apartment suited us well but it is like some hotel rooms - small and there was no stove for proper cooking but instead a microwave like grill.
The elevator was tiny and without a wall to one side which made it a bit of a small thrill quirk. But the apartment itself is beautifully done and very comfortable.
We weren't able to leave our bags after checkout - unlike other guest's experience. Possibly on account of a busy period. That was a bit of a hassle for us but we dropped them off at the Acropolis bag drop which isn't completely secure but worked out and picked it up at end of the day.
Host himself seems like a great guy. Very enthusiastic and friendly. Came up to us just as I walked up to the building.
All in all full stars.
