We arrived in Istanbul at 2 p.m. and had asked Zafer beforehand if it was and he said it was. But when we arrived at his place, he was asleep and didn't hear us call. So the first night we were paniqued because we didn't know where to sleep. We eventually found another hotel at 4 p.m...
Zafer did apologize the next morning...
The room is very very tiny (the bed too) and if you're allergic to cats then this isn't the place for you because the cats is very playful and jumps on your bed, pillow, shoes and stuff...
The good thing was the location. At walking distance from Taksim. Very convenient.
If you don't need luxury then you're good. We were never in the appartment as we were sightseeing the whole time and went out a lot.
