We stayed at the appartement for 5 days during New Years evening 22/23.
The appartement is exactly what is you see in the pictures, spacious and roomy, two large bedrooms (with great beds), a nice living room and a relatively small bathroom.
The building is very quiet, with no noisy neighbors (at least when we were there), and the best feature of the appartement is the wiew from the balcony, with a direct view to the Acropolis hill and with full sunshine from 10.00 to 17.00 (at least in December).
Worse feature of the appartement is the level of kitchen equipement and services. If you expect a fully equipped kitchen like the one you have at home (including basic spices etc), this is not the place to stay.
The area is quiet, and even if you are only 5 minutes walk from the busy Psyri area with all its restaurants and bustling nightlife, the street where the appartement is situated, is quiet and peaceful.
Furthermore, everything is in walking distance, including metro - very nice!
