Staying in this apartment was one of the best experiences with airbnb I've had before. Message replies were almost instant - Panos and Amalia kept answering all of our questions, we've had a very warm welcome (despite very late arrival, Amalia was super positive and welcoming, explained everything to us). The next morning we got helpful tips on what to see and where to eat from Panos, he even went with us to local travel agency to help us book a ferry and welcomed us with local pasteries.
Room was very clean, you have everything you'll need during your stay - towels, extra pillows and blankets, fridge, coffee maker and kettle + some coffee/tea/sugar if you need. You basically have whole terrace to yourself. Streets are pretty quiet at night, despite some cars or scooters passing by from time to time.
Very close distance to all attractions - around 10 minutes walk to Monastiriaki and Plaka, 15 min to Acropolis, around 8 minutes to Syntagma square and metro/bus stop to airport. I recommend 100% - huge thank you to Panos and Amalia for everything :)
