We rented 2 units in the apartment building. Nicely renovated flats in an old style building.
Area was great. Minutes walk to i̇stiklal cad. for food/tea/coffee/shopping, or, to Karaköy to catch the ferry over to the Asian side.
Apartments were charming, clean, and well heated. Small, functional, kitchen and a good size living room for everyone to sit comfortably.
Definitely recommended if you want to stay in Beyoğlu.
There is a charming little coffee shop that serves slow cook Turkish coffee. The address is somewhere around 15-17 Lüleci Hendek Cd.
