My girlfriend and I spent a month in the apartment (September 2021). In general, our stay can be described as “okay”.
Advantages:
The apartment located in a very convenient location, literally 7 minutes from the metro station, bus stop, ferry station Kasimpasha, and Galata Tower, and about 15-20 minutes to Istiklal and Galata Bridge.
There are a couple of shops and a supermarket nearby.
The apartment has nice interior and all conveniences for a long-term or short-term stay.
Although furniture is a little different from on the photos: a small couch instead of armchairs, an additional table for work, and an additional crack on the wall.
Free Netflix (although we are still not sure if it was not account of previous guests ;)
Hatice has provided us with all a short guide about Istanbul and answered for our messages or requests quickly. Although we have not met her in person.
Disadvantages:
This apartment is tiny. Especially the restroom (about 0.5 square meter): if you are higher than average you might find it difficult to sit and fit in the room with the door closed.
The bed is super squeaky. It is pretty comfortable, but it is impossible to move without making noises.
The living room window has a hole for an air conditioner the size of a volleyball, so the change in temperature outside is noticeable inside. Even if weather is good, you will not forgive about it because of mosquitoes flying through it.
I am not very experienced user of Airbnb, so I am not sure if cleaning during a stay is included in the price, but the apartment was cleaned only before our arrival and after we left. So, ask about it if you plan long stay and it is important for you.
