I would put 3+.
There are advantages:
Polite staff; good breakfast;
There are disadvantages: noise from a nearby busy road; the fan in the bathroom did not work and the cigarette smell from the next room entered my room; lighting is not enough;
An old and uncomfortable hotel. It's hard to get close to him. The taxi drivers got confused only once and couldn't find him. A very difficult entrance. The interior is old, there is no ventilation. Panoramic windows sweat heavily in winter that the water from the windows flows like a stream across the floor. They save on everything. They give out one towel for two and put one small bottle of water. I do not recommend it even for the lowest fee.
If there is no personal sraba in terms of location, it is in a slightly opposite and quiet place. The back streets are not a very regular area, but the cleanliness, service and staff interest of the hotel are quite good. I go here on Izmir trips
