I stayed for 3 weeks at Konstantinos's apartment, and I can honestly say it was one of the best-equipped Airbnbs I've ever stayed in!
I was working remotely from Athens, so wifi was important to me, as was having a comfortable place where I could feel at home to cook, etc. This apartment checked all the boxes! The apartment could comfortably hold 4 adults for a long stay. The kitchen was well-stocked with pots, pans, silverware, etc. There is a washing machine to wash your clothes, a drying rack to dry them and a vacuum in case you need it. The AC worked well, and there are several wall units within the apartment. The bathroom has a large window in it, which is so nice for providing natural light! Also, there is a large terrace where you can sit and have your morning coffee or wine in the evening.
The area is PERFECT!! Right on the street are several cute wine bars/bars, where you can have an aperitivo. And then you are just behind the Acropolis Museum, the Acropolis, Plaka and so many options for eating and drinking!
Konstantinos always responded promptly to my questions - no problems at all with communication.
The apartment is on the first floor of a building with no elevator (about 20 steps up). Something to consider if you have mobility issues.
I highly recommend this apartment!! It was a wonderful stay!
