The location is actually a minihotel called Ada Home Istanbul. It offers a great location minutes from Taksim Square. It is also only a 7 minute walk from Havas Bus service to Taksim Square (11TL). The rooms are spartan and clean. Great for a short layover and walking distance to some great walking streets. The location is secured and on a small street. The wifi was very spotty, but works will in the lobby. Mustafa didn't greet me, but instead it was the hotel staff Adam. I would stay again. Thanks!
