Erdal's apartment is in a historical building in the Sultan Ahmet area. It had everything that you would need for a short or long stay. It is surrounded by a variety of restaurant, cafe and shops, and is 2 mins walk away from Hagia Sofia and Blue Mosque. Overall a fantastic place to stay in. Definitely recommend it if you are traveling to Istanbul. Erdal is a great host, he helped us organize the transfer from the airport and did the PCR test right at the hotel. Recommend!
