The apartment is located near Taksim square where you have many things to visit, many restaurants and shops.. The host was helpful with check-in time, and responsive when I texted her. Apartment was very clean and it had all necessary things (towels, shampoos, hairdryer, etc.)
Only bad thing us that only one room is separate from others and have privacy. Other 2 rooms are not really separated from each other and we had zero privacy. Me and my girlfriend went with our parents and it felt my parents are sleeping in the same room with us. One room has no window so it was pretty hot to sleep there (room with 2 single beds).
Also good to know is that there are very steep stairs in the building so might be hard for older people to walk up and especially down the stairs.
Besides that everything was great. We also really liked the kitchen and bathroom. The entrance doors to apartment are thick security doors so you can feel safe there.
