I enjoyed staying for a month there, i could give it 5 stars easily but I gave it 4 stars because of the points below.
Pros:
-Lovely neighborhood.
-Street full of services.
-10 minutes to subway / 5 minutes to bus station.
-Flat full of amenities, you could find rocket fuel with little effort :)
-Generous nice host
Cons:
- Weak drainage in the kitchen basin/sink
- Loud voices most of times of day and night from street, back neighbor, building neighbors, building gate, from the balcony,...etc. if you have light sleep (you will be annoyed very easily)
- Apartment is relatively small is area (normal in istanbul)
