Of the advantages:
Normal prices
The breakfasts are normal, but not very varied
Now the cons:
The street on which the hotel is located is just a horror, there are no sidewalks, only car services, piles of garbage, although Taksim Square can be reached on foot.
This is compensated by a free shuttle service (morning-afternoon-evening) to the square.
There are no cafes within a radius of 300m.
We rented 2 rooms in this hotel for a day, we would have stayed more, but ... The windows were not closed in both rooms, the wind was blowing in the rooms, we rested in early March, it was +5+7 outside at night. When asked to do something about it, the staff responded with the words "okay, we'll fix it" and of course, they did nothing. It was disgusting, the bedclothes were in my hair, there was dust.
The hotel is located in a typical working-class area. Not far from the center. Everything was fine with us there. The breakfasts are good. The staff is friendly. However, they do not respond to emails.
