My family and I had an amazing stay at Can's apartment. The location is top-notch, walking distance to many touristy areas, e.g. Galata tower (~2 mins) and Istiklal St. (~5 mins) and only ~5 mins from tramway and subway stations. The apartment itself is spacious and beautifully decorated and has all the necessary amenities.
Above all these is Can's warm hospitality and excellent communication, which makes the whole experience truly pleasant. He gave us great recommendations for anything we asked for, from where to buy the best Baklava, to the most popular shopping centers and outlets. We felt like locals.
This has been by far our best airbnb stay so far. I highly recommend staying at Can's place.
