PROS:
-Very clean space and fully decorated.
-400 meters from metro station that takes you to airport, just one nonstop train ride.
-5 minutes walk to major tourist shopping district.
-10 minutes walk to famed Acropolis and Parthenon.
-Close to many restaurants and nightlife in the surrounding area.
CONS:
-The bed is a bit hard and made not not the best night's sleep.
-The neighborhood is LIVELY and on a pedestrian street with lots of restaurants and stores, that makes for a late night of loud noise til 2-3am.
-Check in process is kind of annoying with fillingout forms and waiting for email replies (but I understand that they are trying to be as professional and thorough as possible with guests).
-An extra .50€ per day fee for something or another that has to do with Greek taxes.
