My stay at Can's was great- very nice and responsive host, quiet area (which is not easy to achieve in Istanbul). Flat is on the last floor, with an enjoyable terrace. The room is spacious and has everything you need (kitchen and bathroom amenities, stovetop, washing machine).
There are a few local shops close by, as well as a main street. The Shishane metro is about 10-15 minutes on foot, however the road Maps suggested was very uphill. There is also a tram nearby which takes you to the metro.
The hosts were very nice- responsive, proactive, very dependable.
There were a few small things in the apartment that were not 100%, but it was overall great- I recommend!
