I had an excellent time staying with Sapphire, and recommend him strongly to anyone. He was extremely helpful with information on how to get to the apartment, including how to get to Istanbul from the airport. Once we met in person, he was nothing but pleasant and hospitable.
We had very nice conversations and he gave me numerous tips for restaurants and attractions around the city, not just touristy stuff, but proper gems that locals go to. The central location of the apartment was perfect for getting around and exploring the city on foot. There were so many things to see nearby.
The room was great, with a nice big bed and very clean, although I spent most of my time outside. Will definitely come here again.
