Alexis is a fantastic super host! He was very responsive to my messages and even arranged a private car (with a car seat for my child) to and from the airport. The location is perfect, with plenty of restaurants, convenient/grocery stores nearby, and it's about 5 to 7 min walk to Taksim square. The bus stops are very close which is nice for quick transportation around the city (using the Istanbulkart).
I would certain have no problem recommending Alexis's apartment to anyone and I plan to return in the future.
