In general this place is good for staying. Located in the new modern district with stylish buildings.
Apartment has fully equipped kitchen where you can cook everything you need. Also bathroom is awesome. The host was helpful and provided us with all information we needed.
About minuses:
From the beginning of staying there was a strong smell of smoking inside. And opened windows during the hole day didn’t solve the issue.
Also, I would not say that location is perfect. You will need to use taxi or public transport for getting to any sightseeing in the Istanbul from this place.
