Overall it was a good stay. Except some inconvenient like the shower, it leaves water everywhere and a lot of humidity. Other than that it was an easy self check-in and a good place to stay for a few nights. Also another way to get to the appartement from the airport is to take the metro line and get off at Syntagma, then take the bus 856 and get off at Ika, we had our backpacks so we only had to walk 5 minutes total which helped us a lot.
