Mr. Farzin was a very nice host. The place is very close to the pictures and was very clean. It is perfect for a solo traveller but can very easily be used by up to 3 people.
The street it is on is a bit dimly lit and is a bit uneasy to go through it at night. Although right around the corner there are shops and other hotels, with markets 3-4 minutes away in the nearby streets.
Overall, it is very nice for the price and the location is just 5-10 mins from Taksim Square.
If you know Turkish, Mr. Farzin will be the best host you can have, if not then it may be not easy but he was always ready to help.
