When I was looking to book an Airbnb in Athens, the reviews for Kleio's rental were a large part of why I chose this apartment. Let me tell you, the reviews were right. Kleio is a gem of a host and her apartment is fantastic.
I'll start with communication, Kleio was super awesome at responding quickly to any questions I had, and even arranged a car to pick (and drop us off) at the airport. When we arrived at the apartment, she was there to do a quick orientation and show us around. I've been to many air bnb's that have the basics in the kitchen, but Kleio goes over and above. There is a Nescafe machine (forget what it's called) and pods for coffee. You want tea? There are about 10 different flavours in the cupboard. There was a basket with snacks (cookies, chips, energy bars, etc.) And the fridge was loaded with bread, jams, eggs, water, yogurt, fruit, etc. We hardly made a dent in what she had waiting for us.
The apartment itself is exactly as the images show. Great water pressure for the shower too. Location wise, it's situated walking distance from most sites. But should you get tired, taxis are very affordable in Athens, unlike many other European cities. (For instance a 14 min taxi ride home to Kleio's apartment on one of our days only cost us 4 euros.)
I've done a fair bit of travelling over the years, and Kleio's apartment stands out not only because it is a great space and good location, but because Kleio herself is so incredibly hospitable to her guests.
If you're reading this, it's because you're thinking of booking this apartment. Take my advice, do it. Book it now, before someone else does.
