Alaaddin's place is located in central Istanbul. It can get a bit noisy, but that is the trade of for being in the heart of Istanbul. The best part of staying at Alaaddin's is Alaaddin himself. He is caring and friendly, he welcomed us with breakfast and tea. He also gave us useful tips to get around Istanbul and invited us to hang out with him in his café anytime we wanted to. Would recommend to my friends any time.
