This location is perfect. We had three days in Athens and wanted to be near the runs for sight seeing purposes and the apartment is literally minutes from the Acropolis. The place is very tidy and is decorated very modernly. Ira was very kind to greet us on arrival and showed us everything we needed to know about the apartment. Our plane actually landed very early in the morning and she let us check in early since there were no guests the night before which was so nice as we were desperate for a nap.
There is a water heater which must be turned on before showering. We were told to do so about 20 minutes before showering but found that 30 minutes and avoiding full water pressure provided better longevity of hot water. It would be difficult to get 2 or more showers taken otherwise.
It's about a 15 minute walk to syntagma square so this was also very convenient for tours and getting to the x95 bus for airport transfers outside of metro hours.
