Absolute gem of a place. Better than we expected. The view is unbelievable, great location. Almost everything in the old city is walkable. Very clean and cosy. 10mins walk to the SultanAhmet Tram station, and 6/7 minutes to the Blue Mosque/Hagia Sophia. Samet also owns a small cafe nearby which serves some really good food (Elif Cafe).
The streets near the apartment is filled with amazing restaurants, and some with fantastic terraces as well.
Samet is super helpful and nice. Always responded quickly and offered help even when we didn't ask. He brought an army of people/friends to help us move up all the luggages to the 3rd story apartment.
Helpful Tip: Use the Havaist (bus) to travel from Airport to the city, and the tram/metro within the city to save a ton of money and taxi extortions. Buy a istanbulkart (metro card) and load it with money to travel in any of the public transportations. One card can be used for multiple people.
