My friend and I stayed here for two nights in late August. Overall there were some pros and some cons, but we were both generally disappointed with this apartment. I have been to 10+ Airbnb apartments across the US and Europe in the last 2 years and this was the first one that I did not give 5 stars.
The main pro is that the apartment is in a great location - only a few minutes walk to the Parthenon and the vibrant Plaka neighborhood which has lots of restaurants, cafes, and shops. The apartment has also recently been renovated, the WiFi was fast, and having a little balcony was nice.
However, there were a couple items that disappointed us a lot. First, when we checked in, one of the two bedrooms did not have the bed made, and there were no backup linens. We had to wait approximately 50 minutes for the host to bring by linens so we could make the bed, which was especially tough given this was at midnight after a long day of flying. The bedroom was also not cleaned well, with lots of hair around from past guests. Would also note that only one bedroom had AC - so if you need to use both bedrooms that is an important consideration.
Another disappointment for us was the shower. While the apartment is clearly recently renovated, the shower head holder was broken so we had to shower while holding the shower head, which is not fun after getting home from a long sweaty day of walking around. We were told that they would try to fix it the next day, but never heard back from them again on this. They also only provided tiny bottles of 2-in-1 body wash / shampoo, and no conditioner, which felt rather cheap. If you go, would make sure you bring your own shampoo.
Lastly, we asked for them to call us a cab to the airport and the driver (a friend of the host) overcharged us- if you go would make sure to call your own so you can get the standard rates.
Overall, this apartment has lots of positives but some significant downsides - if you book would just make sure you are aware of them in advance.
