hi, I stayed in this hotel few times during past 5-7 years , mostly for solo business trips and main reason of my stay been the location ,
rooms interior is outdated while its generally clean,
bathrooms are old with shower curtains ,
I would recommend asking room on the entrance side street as other part with pedestrian street was noisy at summertime,
otherwise the hotel is at the very heart of Kifisia, an opulent neighborhood of Athens with lots of cafe's , restaurants' shops etc. If I choose the stay again it would be the location.
Must add that reception staff is friendly and helpful for any issues.
