Great place to stay. The location is amazing as it is in a very lively area with a lot of restaurants/shops within walking distance. The Kadikoy port, Kadikoy Metro, and bus station are a 10 minute walking distance which is extremely convenient. As someone who works from home, the internet was fantastic along with the work chair and desk.
This was not an issue for me but it can be for others, the noise throughout the night. As this is a lively area, the outside noise is constant until 4am.
Overall, I highly recommend staying here. I will definitely be staying here again with my next trip to Istanbul.
