This apartment is in the best location! I took the metro from the airport and it was just a short distance from Syntagma station. It is right on Ermou which is a pedestrian shopping/restaurant street. It could be noisy at night but we didnt need the windows open since the AC worked great!! And so it was pretty quiet. Easy walking to the Acropolis, the Monistiraki and the Plaka. We also took the metro from Monistraki Square to the port for our cruise. No taxis were needed.
The apartment was clean, and well supplied. The bed was comfortable, but not so much the pull out couch, as it was pretty hard. Nice bathroom and kitchen. Building felt safe.
