The apartment is great, very clean and cozy. We were three adults and a toddler, felt very comfortable. The garden wasn't very useful to us as we stayed during winter time, but it does have a great view and should be very nice in summer. There are cats in the garden as other reviews mention, they are friendly though.
The most impressive about the apartment was a very responsive host. He promptly and efficiently helped with all our questions, found playgrounds nearby, recommended restaurants, even ordered taxi for me during the night. We felt very welcomed and taken care of.
The area around the apartment is historical, has a lot of character, and great restaurants. A short walk away is Galata Port with embankment and restaurants. The trams stop is a short walk. But I must say that Cihangir is hilly, especially the walk to the tram stop. It is no problem for adults, but was challenging for us to push the baby stroller up. Although you can always call Uber. Great experience over all!
