I stayed here twice in the past couple of weeks shouldering onto a cruise that I was taking out of Athens. Unfortunately, I forgot to take pictures.
I was in a deluxe suite for my first stay and an executive suite for my second. Both stays were great. The rooms were well appointed and comfortable. Service throughout the hotel was friendly and prompt. I didn't really use many of the facilities; I skipped breakfast both days and I'm not a pool guy. The rooftop restaurant had some good cocktails and there didn't seem to be much in the way of restrictions for use of the welcome drink vouchers. I know there was a note earlier in the thread that SNU's couldn't be used here, that is no longer the case. Both of my stays used SNU's from a basic room upto the deluxe suite (which is more of a junior suite) and my second stay was given a further upgrade to an executive suite (proper 1 bedroom suite).
Overall, I'd definitely recommend the hotel. Between the rooms, location and service, I was very happy with the stay. Using the SNU's made it a fantastic value during the summer travel peak.
