Stayed 2 nights at the end of October. Perfect location next to the Plaka old town if you are on a quick visit and want to do the tourist stuff. The staff were friendly and professional. The room was clean and modern, not 5* luxury but perfectly decent. To note, a personal bugbear, they charge a lot for internet access unless in the lobby where it's free. If you pay the OTT amount for access it is not a great connection. I personally would rather hotels put an extra 10 Euros on the room cost and told me I had free WIFI. I can't remember what we paid but it was over 20 Euros each for 24 hours for high-speed access which really riles me.
The view from the rooftops was great as promised. Breakfast was chaos. Everyone arriving at once, too few staff trying their hardest to turn around the tables and re-lay. Breakfast food basis but okay. We didn't eat there in the evenings as it seemed expensive and the ads we saw in the lift were for pasta when we wanted to grab as many Greek food opportunities as we could.
I would recommend the hotel but would recommend to them that they sort the internet thing. It's a rip off that leaves a bad taste when otherwise we had a good stay.
