Apartment owner and his assistant are very nice. Signing in was very easy. The apartment is clean and contains everything a person needs. The location of the apartment is close to Trump Tower in Sisli area but the neighborhood is not good enough. I have another note which is that the owner contacted me to ask for a copy of the passport. And that is according to Turkish laws, he told me. Although this was not mentioned when installing an apartment reservation via airbnb. In general, I can say that I was comfortable staying in this apartment.
