I really enjoyed staying at the apartments. the apartment was very modern, very clean and had all the amenities I needed. Everytime I needed something Nida and Yildiz took care of it very quickly. She also took care of the transportation from the airport since I arrived very late.I appreciated the daily trash cleaning and also the weekly new bedding. It is very close to Istiklak street however the neighborhood is pretty shady. I had some not good encounters. Be aware Beyoglu is very hilly and also this apartment has many stars up and down. Even though I didn't like the neighborhood I felt very safe because of all the gates and thick door. I had some problems with the washing machine. The biggest letdown was the WiFi, very unstable and I had to restart it at least 3 times a day and sometimes even that didn't work. Some days I was without WiFi for several hours so I definitely recommend getting data sim card, the internet on that is excellent. You can get 25gb sim card for 160TL with some hassling. and top up is 100TL for 25gb.
Thank you for having me, I hope you will be able to fix the WiFi, after that this apartment will be perfect.
