Yusuf and his colleague are unbelievably helpful and hospitable. I received tea upon arrival and a full explanation on where to go and what to see in Istanbul.
The reception is 24/7 which is amazing!
He helped out with calling taxi's, delivery pizza, booking tours, helping to carry my Luggage upstairs and down stairs. Also they are very interested when it comes to how your day was, what did you explore, what places did you like most etc...
I would definitely recommend this place! Oh and it is at walking distnce of almost everything :)
