Sertaç’s place is incredible. Outstanding view from the terrace/rooftop. You can choose to have your breakfast looking at the Marmara sea or the Blue Mosque. This for sure will give you more energy to explore the neighborhood and the rest of the city. Blue Mosque and Hagia Sofia about 5min walking, besides many grocery stores on nearby. Another thing worth mention is that Sertaç arranged a transfer from IST airport to the hotel for a good price. Since my flight arrived late night, I didn't want to depend on find a taxi at the airport. For sure I will recomend Sertaç’s place for my friends coming to Istanbul!
