Great apartment in excellent touristic location in old city near many sites such as the Blue Mosque and Hagia Sofia. We rented both units at the same time which was perfect for our family of six but with two bedrooms with 3 beds each it could accommodate far more (up to 10). This also gives you two kitchens, two bathrooms and two washing machines. The neighborhood is quaint and old and the neighbors are friendly. In my opinion it would be ideal for 2 to 3 nights. after that the hassle of getting through the crowds to see other parts of Istanbul gets a bit much. there's so much to see in this city of 20+ million people outside Sultanahmet area that other areas would allow for quicker travel to other parts of the city. That said, Selim is a great host and helped us with a few things including airport transfer, printing covid test results, and more. he's a really nice guy.
