Mustafa's apartment is in this amazing, almost a century old building located a stone's throw away from the Blue Mosque and the Hagia Sophia. His family has been residing there for over four generations. We were a group of three adults and a toddler. He had made arrangements for us for pickup and drop off from the airport (for an extra fee, highly recommended) was seamless, and very comfortable. He greeted us in person upon arrival, showed us around the apartment, made us feel like his family, was very welcoming.
The apartment is fairly spacious with 2 bedrooms, and a nice kitchen and a bathroom, with a washer and dryer. Living room has comfortable seating, and a nice TV with netflix, prime etc. Both bedrooms have cute little balconies with partial sea views. The decor is spartan and beautiful, and has a lovely old world charm to it. The location cannot be beat, walking distance from every place you'd want to visit, in the heart of Sultanahmet. Mustafa is readily available, quick to respond if there are any issues, always willing to help. We had a comfortable stay here, no complaints. Apartment is on the third floor, no elevators, the stairs weren't a big deal however, he helped us with our luggage both when checking in and out. Would happily stay here again if we are ever in Sultanahmet again!
