We stayed in the apartment for 5 weeks. Most of the necessities were available, or the host would try to get them for you. The neighbourhood is amazing, we are a working couple and there are a lot of good coffee/work spots closeby. We also went to the gym around the corner where you can get a month subscription.
The house itself is nice, the beds are good. We did miss a place to sit outside, the balcony is quite narrow so it's only use is for drying clothes. The bathroom is a bit small for a longer stay. However I would recommend this place, even for longer stays, because the basics are good, the host tries their best to help you, and the location could not be better in whole of Istanbul.
