The host family are very nice and really helpful, you can communicate with them in English German, unfortunately, I don't know whether they speak other foreign languages, the most important thing is they are welcome, the location is also good and you can go anywhere, but for Istanbul the old city, the ups and downs are quite normal.
always the best thing in Istanbul is that you are staying with a nice family
I'll be back in October
Have fun in Istanbul, a fantastic area
