Great location, easy access from airport. From Ataturk Int. take the metro and then tram to the Cemberlitas stop. From there it is 10 minutes walk downhill. If you have baggage catch a cab. All main tourist attractions are within walking distance.
Check-in is quick and easy. The staff is helpful and friendly. We loved having breakfast in the beautiful garden. There was always plenty to choose from - yogurt, fruits, cheeses, bread, salami, cornflakes, veggies, some local food, pastry, tea, coffee, juice, etc.
Rooms were recently renovated, although not everything worked perfectly (but exceeded Turkish standards). The apartment was perfect size for three adults. Little kitchenette would be even more handy if it was stocked with some cutlery or wine opener. But it was nice to have fridge and the ability to make tea and coffee. Plenty of restaurants around.
