As a frequent visitor to Istanbul i can say that this place was way better than others i stayed in the past on the same area. It looks axactly as sown on the photos. Small but new and clean. For my needs and comfort its lockated on the most convenient point of Beyoglu.
There were some issues with the heating and the boiler for hot water. Don't know if it was the snow outside that made me feel like needing even more heating but Missy really tried to get rid of it immediately.
Difinatley i would stay again on Missy's next time.
