Very very lovely apartment on the top floor of a quiet residential building. Convenient location to walk to the nearby metro stations or even just walk directly to the major historical sites. The decor and design of the apartment is excellent, the TWO large porches add so much usability, there is a dedicated coffee station, and the kitchen drawers and drawer system is excellent.
My only issue with the apartment was an inability to consistently get hot water out of the shower. This apartment (like most Greek apartments and many Greek hotels, apparently) use solar heating for hot water with a backup electric heating element that you have to manually turn before you want to take a shower. So in the mornings or on cloudy/cold/windy days, it might not be as warm as you want even with the backup heater on. That was my only complaint, and since I travelled to Athens in winter, it was probably a timing thing.
