The Resadiye is often the cheapest discount option in Istanbul on hotel search engines. There's a reason for this. The location is not bad, being in a parkish neighborhood near the picturesque Fatih mosque, and a short cab ride from the Old City. However, the rooms are tiny and poorly equipped, they have little temperature control, and they're subject to street noise. Worst of all, they often book out to school groups, which means dozens of totally out-of-control kids ging berserk in the halls until 1 AM or so. The staff is unwilling or unable to deal with that situation, which means that if you expect to sleep, you're right out of luck. Avoid this hotel!
