Mehmet and everyone working at the building were very helpful, always responding very quickly to our messages regardless the time! The location of the room was very helpful, almost right on Istiklal! That came with the small disadvantage of pretty loud music until 24:00 but we didn’t mind.
Finally, the room was obviously recently renovated and modern, though with some apparent humidity and mold issues on the wall. In addition, the place wasn’t throughly cleaned, with dust under the bed.
I’m general we were satisfied with our stay, it was pretty dissent concerning the price. Recommend if you travel on a budget and location is important to you!
