I honestly can't think of a better place to stay in Athens, period.
The location is unbeatable, the apartment is lovely, hosts are super thoughtful. Anna welcomed us and was so nice and accommodating and made sure we had everything we needed. They also left some some food for us which is such a nice touch. The apartment has literally anything one could ever need. And the shower is really good (I am very picky with showers :D).
Now what sets it apart from everything else, including top hotels, and what made us book it in the first place is the amazing balcony!!! It is such a treat to come back home after walking up and down Athens all day and be able to relax there. The view is great but if you want an even better view you can access the rooftop and watch the sunset over all of Athens and the acropolis, all by yourself. This is obviously awesome any time of the year but in times of coronavirus it feels like an absolute luxury to have so much space and not have to worry. We recommend getting some souvlaki and lukumades and enjoying it :) (Anna has some really good restaurant suggestions!)
It's the kind of place that you are sad to leave because you feel you didn't spend enough time in (and we spent quite a bit of time there).
We will 100% be back.
