A great choice for one person or a couple travelling to Athens. Very good location, close to main city attractions and with rather quite neighborhood at the same time.
The apartment basically had everything I needed for my stay. The only drawback was that the shower was not stationary, so I had to always hold it in one hand.
Check-in was pretty smooth, George and his assistant were kind enough to organize an early check-in for me, so I didn't have to walk around the city with my luggage. Great place overall, highly recommended.
