The location of the apartment is awesome - it is within walking distance to all of Athen's sights. The longest walk is maximum of 30min to reach an attraction.
The apartment is very clean and has all amenities as described. The host communicates well and timely the details for check in and check out and the instructions were very clear.
The location is central so sometimes it can be just a bit noisy during the night - for me it was not too bad at all. However, there is an "exit" sign in the room - which most likely is very good for safety - but at night it is bright. It's in the direction of the bed too so sleeping was not exactly comfortable for me.
