We had a wonderful stay at Andreas's and Roula's Plaka apartment. The property itself is beautiful -- and exactly as described (if not better). The location is excellent for exploring Plaka, Acropolis, etc. However, what really makes this property special is the hospitality of the hosts. We came directly off an overnight flight from the USA and they were very accommodating in letter us store our bags so we could explore Athens while the property was being cleaned from the prior guests. They also worked with us to complete the cleaning as rapidly as possible so we could access the unit as soon as possible.
I would highly recommend both this property and these hosts.
