Honestly we were a bit diasppointed as we checked into the apartment.
The Checkin via Lockbox was very easy.
In the flat everything seemed a little rundown, as if the pictures of the flat were taken quite some time ago. Also the AC didn't cool down the place at all (though it was running very loudly), the towels were clean but full of holes, the toilet flush kept running, the door lock didnt work et cetera.
The huge balcony was definitely a plus.
The location of the flat is alright, though there are some nicer areas around.
Overall the place was okay for one night, but for the rest of our stay in Athens we chose a different AirBnb.
