We stayed 6 nights in this hotel, and it is by far the best Hilton and one of the best hotels that I have stayed in. I judge a hotel by two factors: staff, and the quality of my sleep. The staff in the hotel are simply great. They are always helpful and extremely courteous. From the front-desk staff to the concierge and the bellboy I cannot praise them enough for their treatment of the guests. My wife and I are sensitive to noise and are picky about the bed. I am particularly fussy about the HVAC system. Our room on the 17th floor was so comfortable that we had absolutely no trouble sleeping for the 6 nights that we spent in this Hilton hotel. The bed was great, and the HVAC worked perfect with absolutely no sound, even though the outside temperature fluctuated between 8C and 25C. As other reviewers have mentioned, the hotel is located in an upscale business district. However, we had no trouble with taking the taxis to the old town for a minimal cost (about 30 TRL). The breakfast buffet at the Hilton is wonderful with a huge variety of foods, including Turkish breakfast. However, we were disappointed with their dinner selection. For dinner, I recommend the four restaurants adjacent to the hotel that serve a combination of Western and fusion cuisine (but no Turkish dishes). They also serve a variety of beers/wines.
