We wanted to stay in the old city/Sultahnamet, but the issue we came across was that most hotels there are boutique and small. The bigger ones were on the other side across the bridge, but we wanted to be near the main historical sites. Four Seasons Sultahnamet delivered in ways we could not have imagined. They gave us early check in at 9 am, upgraded our room so we'd have more space with a baby, put a crib, basket of baby goods, bath towels, and rubber ducks for our baby without asking. Everyone acknowledged you whenever they saw you. The rooms were exceptionally clean and there's room service twice a day. They even notice little things you may need i.e. makeup brush holder. The beds are so comfortable that we got some of the best sleep ever. The staff is SO friendly. I could go on and on about this place! Plus, it was a 3 minute walk to the square where Hagia Sophia and Blue Mosque are, so the location was perfect!
