Very cool place to stay. Near to everything you’ll need and expect to see in Istanbul. Also, great and tasteful places near by. Try to go Kahvalti sokagi (Breakfast Street) in the morning. Many many bars and cafes to go at night.
Any transport you need is near by. You need to walk like a minute to get a taxi, but I don’t think this is a huge problem.
Come here if you need some quality time in Istanbul.
