It's a good deal for the money but not the best place. There is nothing wrong , it is clean, an average room but had old vibe.
There is no problem from the host side, it is just I had few baggage and the area is in extreme downhill, Walking to Hava bus stop will be really tough with all the luggage. But if you have small carry on then it could work. The building is very old and have this old building smell. They have a full kitchen but nothing to warm your food, so a micro woven would have been nice.
But i paid 20€/day, so good deal. It was just, i had stayed in other better places in Istanbul with similar price.
