Spiro's apartment is clean and cozy. The modern touches in the apartment were great. The location is not quite close to the attractions but is about a 20min walk from the apartment. The closet metro station is about 10-12min walk but easy. You can walk to the Acropolis, but having a metro pass is quicker. Lots of cafe's and restaurants close by as well as a craft beer place.
If you need a ride to the airport he can arrange a taxi that will pickup and drop off if you need it. It was worth it as it is more than a 40min car ride to the airport.
