I stayed in Istanbul 6 times before and this place was not a good choice. Some strong positives as well as negatives that guests should consider based on their own preferences. I won't stay again and do not recommend.
Positives:
Great location, 30m from galata tower, lots of restaurants, bars, shops
Easy to find apartment
Responsive team - Mustafa we spoke to & was responsive
Flexible on check in/out time
Great roof top view of city (but only allowed till 10pm)
Negatives:
Very stained/dirty/old furniture, sofa fully covered in stains
Not look like pictures on advert, badly needs maintenance and repair, the bathroom tiles/floor are peeling off paint, dirty tiles, no bathmat
Grinder pump system in bathroom so cannot flush toilet paper
Main view from apartment is of a dirty office building and street
No spare towels/bedding (only given later when requested)
Never communicated with Maha/Chiko - (mainly with a mustafa)
No bedroom door for privacy
Building work on above floor
