We spent five days in the apartment. It is located close (within walking distance) to the most important ruins. If you do not want to walk there is a taxi stand nearby as well as a trolley stop.
The apartment suited us well as I love to cook. I was able to cook most breakfast and don't dinners while I was there. There are also places to eat very nearby which we also enjoyed.
The host deserves 10 stars. The host communicated promptly on our queries of all kinds.
Should we return to Athens, this is where we will stay again. we recommend it highly
