Would very much recommend this apartment and host.

Myself and 2 friends stayed for 2 nights and Oya was quite accommodating of our late evening arrival and early morning departure.

We were welcomed with some delicious homemade biscuits (cookies) and the apartment was nice and warm despite the temperature being -3 Celsius at the time (an extreme and rare cold for Istanbul).

There is a supermarket within a very short walk and everything we could possibly need was provided.

I likewise found that Wi-Fi is available and it didn't smell of smoke.

It is a pretty quick trip from the city centre by public transport which is within walking distance (6min). The transport itself was some of the cheapest I've come across in Europe.

One of the bedrooms was a little too bright for our liking and the showers did not run as hot as we would have liked (i.e. very hot) but these are personal preferences and I would recommend her apartment to anyone and would stay here again should I ever return to Istanbul.
