The dark secret about this hotel is that it is directly opposite the huge City Hall in Istanbul, and that building runs the most massive air conditioners I've ever seen (classic Crane Company multiple-fan cooling units, presumably from America), These make such a terrible noise -- such a high-pitched, piercing drone -- that you feel like you are bedded down at the end of an airport runway. To top it off, that 24-hour-a-day din is mixed during the day with a heavy drone of careening cars on one of the city's major arteries, less than a block away. The result is, quite simply, that you can't open a window, day or night. So...only if you're someone who can sleep sealed up with a cold and capricious air conditioner breezing right over your head, will you be comfortable in this hotel. I've read the other reviews, and can only concur that the reception-staff on duty while I was there were the least pleasant and helpful people in that position, that I've ever encountered in an international hotel. When I tried to change rooms (to get a bit away from the noise), they blithly tried to more-than-double my room-rates (for the same sized room), and skillfully obscured the whole exchange by steadfastly refusing to speak or understand any English. The rooms were adequate, so long as you don't need to watch TV (nice-looking flatscreen TV mounted in the wall, but no controller available), and you bring your own soaps (none were provided).
