One of my favourite stays. Communication with Konstantinos was outstanding as was his helpfulness and friendliness.
There is an elevator to the fifth floor and then stairs to the apartment on the sixth. The apartment is clean, bright, well-equipped and has a great balcony overlooked by the three main hills of central Athens (including the Acropolis and Parthenon). The kitchen is really well stocked and even has a dishwasher!
Location is vey good. Koukaki is a great area to stay; safe, good restaurants all around (lots in Dragou). Lots of supermarkets. Close to Syntagma and the inner city, the Plaka and Acropolis Museum - all within an easy 30 minute walk. Closest metro station, Sygrou-Fix is about 10 minutes walk.
I had a very comfortable six nights at Konstantinos’s apartment. I’d highly recommend it for a single traveller or couple.
