This is a great central place to stay. Close to many very good restaurants, cafes and Taksim and Isteklal. Easy to get around via the tram which is around 10 min walk. It can be a little tricky for taxis we found due to our location it was hard for some taxis to find the place due to the winding roads and narrow lanes. Keep in mind this location is around many steep hills so be prepared for this especially if you have any mobility issues.
It is also quite noisy at night, we found during our stay dogs barking constantly at late at night and loud noise from traffic and people yelling outside. Something to bear in mind if you are a light sleeper. Overall we had a pleasant stay and communication and hospitality was great!
