Wonderful hotel in a great location. Fantastic breakfast spread. The restaurant manager at breakfast was especially great. Provided some nice insider tips when asked and could tell he was working hard to train the staff to keep up top notch service.
Front desk was ok. Had some minor issues that they didn't seem too eager to solve, but were generally positive.
The major disappointment of the stay was that the bed is definitely not an American King Size bed (as appeared to be advertised). A queen is not small, but not what was expected. Also, room furniture not as pictured in photos. partly went with a nicer room for the little couch that seems to be in those rooms. This was not there in ours. Not dealbreakers, but false advertising never feels good.
It was a huge bummer that the roof was closed. Their website said that it was set to be open for our dates in March, but it was not. When I pointed this out, I was told that I was wrong and that the website said April. Unfortunately for them, this was easy to disprove. Given that this is a key reason to book such a hotel in Istanbul, very big value loss. They made it up to me with a few strawberries at 7pm right before dinner (lol). Not 5 star service.
