I really enjoyed staying at this place and I would rent it again and recommend to others.
Pros in my opinion:
-excellent location in terms of being at the center of Istanbul, close to metro and other public transport.
-also has good access to close by cafes, bars, markets, restaurants (esp in Nisantasi and Taksim)
-place has a very pleasing outline and look. It was also nice to spend time here.
-Nice bathroom, good water pressure in the shower, no weird smell.
-Place is cleaned well.
Minor cons:
-on the 4th floor without an elevator
-old apartment with less than ideal insulation (could be a problem especially during winter)
-living room windows see the windows of the buildings right across so there is less privacy when the blinds are lifted.
Also communication with Anne and the people helping her was very good. They gave me a good check in and check out experience.
