Great location if you want to explore some Athens nightlife! We were only in Athens for a day and planning on flying out early in the morning. The flat is located in a bit of a party district which suited us perfectly-- many of the places we're still going at 3am when we had to catch our flight! It is also central for restaurants, rooftop bars, souvenir shopping, and of course gelato.
Alexandros provided clear check in instructions and helped us book a taxi for our trip to the airport (as well as told us the flat rates for common trips).
Also, the shower is amazing. It takes a second to warm up but the water pressure is incredible. Just what you want after a long day!
