Suzan's home is great for visiting Istanbul. It is located in 10 min walk from Taksim square and metro station. Buses operate every 30 min from New Istanbul Airport and Sabiha Gokcen airport to Taksim Square. We arrived at midnight but it was ok. The room is spacious and comfortable. Fortunately, language barrier is no problem because her hospitality and her sister manage everything :) Suzan prepared breakfast for us and had it together on the balcony with nice view. We talked about books, movies and some local tips during the breakfast.
I recommend highly and you don't regret it.
