We stayed in the Lykavittou flat for three weeks - it felt like our home away from home. The location is amazing and can't be beaten, an easy walk to everything in Kolonaki but also central Athens. The balcony is incredible - very rare to find a big balcony like that through Airbnb in Athens - and the flat's position on the fifth floor not only made it very bright (and do note, there are very good blackout blinds in place, too), but also very quiet, despite it being so central. The bed is very comfortable, and the flat was overall very clean. The kitchen is well equipped, and when there were a few additional things we needed for it, Upstreet provided them immediately. The TV has every channel you might want + Netflix. We'll certainly stay again.
