If you're traveling alone and you don't mind noise, this place is great. The mattress was excellent and the space was very clean but for the smell of cigarettes. It's very close to the best nightlife in Istanbul. Too close because the room is not "soundproof" as stated in the listing. Additionally, the room was comically small for two people, like a Japanese business hotel. The pictures don't represent this accurately. We had a choice of blocking the exit or blocking the bathroom with our single piece of luggage. The Wifi was broken, dropping devices every two minutes or so. The staff are friendly and helpful. The included breakfast was excellent, served by the café next door. There are better spaces in this price range, but if I was a young smoker who wanted to party, this place would be perfect. If you're a family, just stay away from Istiklal altogether.
