The room I had was about as spacious and comfortable as you could wish for -- all modern conveniences, quiet, and clean. Downstairs, I used the sauna and the gym. Both were clean; the gym was well equipped, and the locker room was convenient and safe for valuables. For the money, this was a really good deal. I cannot speak for the other amenities -- steam room, massage, pool -- because I did not have a chance to use them. Same for the restaurant, since I wanted to explore the neighborhood.
The drawback of the hotel is the dreary location. You are well away from anything touristy here. However, there are good restaurants just a couple of blocks away for traditional Turkish specialties, all very tasty and inexpensive.
