Tolga place had a very good place, near to taksim square (hundreds of meters away) and 1 cross road away from istiklal street where the great restaurants are.
the surrounding is good and peaceful also the worker's in neighborhood store knows tolga well and welcome his guests so you will feel as if you are in your home.
1 remark to mention is that the bed could be better and more confortable, and the shower has a small problem in water flow but it was working fine.
overall I recommend it and the place is worth the cost.
