First off let me say the apartment is larger than the photos make it look like. Very comfortable and modern with everything you will need.
The location is ideal. Close to great restaurants and within walking distance of the Parthenon, maybe a 15 minute walk.
The apartment itself is very clean, modern, with AC (huge plus for my family since we are from Miami), and hot water. Wifi also worked well. George also left a few breakfast items and coffee for us, which was great as not everyone does that.
Most importantly, it was very easy to communicate with George prior to check in. My flight ended up being several hours late and the rest of my party arrived before me. I was able to let me know, and he responded quickly knowing that they would be checking in before me.
Overall, great experience and would recommend to anyone!
