Location is good, 15 min by foot from Taksim Square (arrival point of the airport transfer buses). Area is sweet overall, but noisy at night (I was lucky enough to stay at Ramadan, where some guy was banging drums at 3 am outside to wake up people for pray).
It was hard to find an enter to the apartament due to provided photo and real door were completely different. I did a call for host but they didn't respond in time. I was lucky to get the right spot with the random food raider.
Shower solution is questionable: bathroom is really small and it's impossible to shower without flooding the whole floor.
