This apartment is the best Airbnb I have stayed at (and perhaps hotel as well). Perfect for a family (max 5 people) or two couples. The amenities are well thought out and beautifully appointed - and includes all amenities you would find in a 5 star hotel. The apartment is as described by the host, and even more beautiful to see in person (no exaggeration). I would recommend staying here over any hotels in Athens.
The area Kolonaki is very safe and a short walk to Syntagma Square, Ermou Street and a short cab ride to Mount Lyccabetus. Plenty of restaurants and cafes around and designer shops.
The best part of the apartment is our host Romanos. He organised a minivan to pick us up to and from the airport. He also welcomed us at the apartment and gave us some very helpful tips for our few days in Athens. We had an early check in and mid afternoon check out, and Romanos accommodated our check in/out time requests.
Highly recommended to anyone staying short or long in Athens, and would definitely stay here again!
