Excellent breakfasts, staff, clean, located in a convenient location. Near the metro, tram, many attractions. One of the disadvantages is the elevator by card, you can only go up and down from your own and to your own floor. And if you're a company and you're on different ones?!
I liked the hotel, it was very clean, pleasant service, decent breakfasts and very tasty cafes in front of the hotel, where they cook very tasty meat.
The very center, everything is nearby, shops, pharmacies, the embankment, but prices are higher than the average in Istanbul because of the location. I recommend
A normal hotel, friendly service, clean rooms, good breakfast. There is no good restaurant within walking distance, unfortunately there is no lunch and dinner at the hotel, but if the task is to be close to the sights of the center of old Istanbul, a great place.
