Wow. Everything about our stay in Kleio's apartment was fantastic. When we booked Kleio was quick to respond to messages (quicker than me!!) and provided helpful information. She also arranged a taxi to and from the airport and was at the apartment on our arrival to show us around. Kleio is a great host - she is very friendly, showed us the apartment and gave us some helpful tips for sightseeing in Athens. The apartment itself was lovely - quite spacious with a large open plan lounge and kitchen area, with the bedroom on the mezzanine upstairs. The apartment has everything you need to make the stay comfortable, from a TV and Bluetooth speaker, coffee machine, kitchen and even a washing machine. Keio had very thoughtfully stocked up on various things and said that we could help ourselves, so there was water and milk in the fridge, lots of teas and coffee, some snacks and other food, and even some wine and beer. The apartment was very clean and tidy, with an outside courtyard which was nice for sitting and having a glass of wine (we went in November and were very lucky to have mid 20s temperature), and is in a good location - an approx 15 minute walk to the Acropolis, to the city centre and less to some local bars and cafes.
All in all, I could not recommend Kleio's apartment highly enough if you are staying in Athens and are looking for an Airbnb!
