I liked the location, the internet was good, very easy access to the subway and Taksim. A lot of places to find food. I liked the balcony and the limited view to the Bosporus. Very responsive host.
We didn't have any major issues with the house just a few things which I am gonna reach out to the host separately and I am sure they will be taking care of them.
Overall, we had good experience.
Things to keep in mind:
You have to meet with the host to enter the house so make sure you let them know at least 15 mins before arrival even if they say less than that.
There won't be any washing supplies so if you are planning on staying longer and using a washing machine make sure you have a detergent. There is also a store nearby where we bought water and other necessary stuff.
You will have to deal with a lot of uphill and downhills in the area, so make sure you are ready for that.
There are a couple clubs nearby so you will get to hear a lot of loud music.
