Our Stay at the Raven Suite was wonderful! Mr. Tamer communicated the whole time perfectly and even organized pick up and transfer back to the airport for a small additional budget. Check In and Out went with without any complaints. The Studio was functional and exactly like described with a balcony we sad regularly on. The location itself is perfect to discover the vivid neighborhood of Beyoğlu and the European side of Istanbul.
Only one thing to add, as it is incredibly central, I recommend Oropax for a decent sleep, but as we kew that in advance, we adjusted and it wasn't a problem at all.
In a nutshell: Highly recommended.
