Booked the Niles for a long weekend in Istanbul to celebrate a big birthday in couple. Glad we did we had a great time. The room was big, clean, nicely decorated and the bed comfy. Very early March but the hotel heating works great, our room had floor heating. Staff were very friendly and helpful. They even left a nice cake in our room on our birthday while we were away. The location is great so close to the grand bazard and the blue mosque. You can go to most places by foot (if you like walking) or public transport as the tram stop is very close. Breakfast is served in the lovely roof conservatory (which doubles up as the hotel bar during the day). Breakfast is the typical Turkish breakfast, a nice change from a continental or English breakfast. There seem to be hotels everywhere you look around Istanbul, but I can't imagine many being so good as this one.
