Pros:
The view is beautiful, especially at night, and the apartment is fairly central.
Cons:
Check in was a complete mess, my partner and I ended up stranded with all of our luggage and had to rent a locker in the city because the host was not ready for check-in on time. He even went as far as to change the check in time on the listing while I was outside (screenshots from before to prove it) and try to gaslight me that I must have confused it with another listing (he changed his tune when I showed him the screenshots, but I don’t like being lied to by a host).
After 2 hours we were able to get in, but it was quite stressful to be stranded in the middle of Athens with lots of valuable luggage.
Also, lots of mosquitos in the bedroom, bring your own bug spray! I got bites all over after only two nights.
Overall, it’s a good experience for a few nights but I wouldn’t recommend a longer stay. If anything, get a cheaper Airbnb (there are many nearby) and take in the view from the variety of rooftop bars and high class restaurants nearby.
