At the door of this hotel there is a reference to four stars, but I can say that the quality (and size) of the bedroom as well as services, are clearly of a three star hotel. Just by way of example, I can tell you right after we arrived, they took us to a room that was already occupied by other people!

Good for one night – but wouldn’t want to stay for any more. My wife and I stayed here during a tour of Turkey. Our room had a noticeable smoky smell and that was the case with most of the rest of the group we travelled with. Dinner and breakfast buffet was adequate. Nothing really stood out. The room had a tea kettle which we used for our morning coffee. The bar had outrageous prices. A beer was $18 lira - about $12. We went outside the hotel about 5 minutes away and found a restaurant which had beers for $7 lira.

I often stay at Radissons, this one is clearly one of the worst. The quality of the building itself is poor with bad heating and isolation, Even though I was pretty high up and in a business suite, I could hear the heavy Ankara traffic outside all night and I was freezing. Also, something odd happened to me: During my 3 nights stay, I had someone ringing my door bell a couple of times 2 nights in a row.... vanishing when I woke up and finally got out of the bed to check. Restaurant serves OK food and has a buffet. Avoid it if you can as there are plenty of very nice and cheap restaurants in Ankara.
There are many better choices of hotels in Istanbul, the Radisson is far too expensive for the service you get.

What I’ll remember from this hotel forever is the amazing view over Ankara we had from our 10th floor business suite.
We were upgraded to this business suite and from what we heard from friends, our room was a lot bigger than their double rooms. Bathroom was not the best (we had trouble in taking a shower) but the room was fine and clean. And the view over Gençlik Parki and Anitkabir (Ataturk’s mausoleum) was breathtaking!
Although with a variety of items, breakfast was kinda messy, cause there were too many groups eating at the same time. Tables were too close from one another and it was very difficult to eat while people were passing behind you (for there was no space…).
Good hotel for business purposes.
