Ram's apartment is really great. Firstly, he is an interior designer himself and he designed this place himself. It is a really nice place to be inside. The terrace is great and has a beautiful view, its nice to sit out there and cool down after a hot day in Istanbul.
The location was quite good too, 15 mins walk to Taksim square and easy to walk down to the harbor.
I think just be aware this apartment is on the 6th floor and there is no elevator. We didn't find this a problem, it's a beautiful old building which was built before elevators were a thing.
Ram was a gracious host and was able to help us organize a transfer from the airport. We didnt need anymore help with our travel but he was available if needed.
It's a good place to stay.
