Great property management company, however, I spent time reading all the reviews and selecting a place and I wish someone would mention that it's not really nearby Taksim square. So here are few things that might be important for someone:
It's a nice place on a quiet street, 2nd floor with steep steps. it's a 20minute walk to Taksim square or a 10 minute bus ride + walking to the bus. You are basically in the middle of a quiet residential neighborhood NOT anywhere near the tourist attractions. You need a gas lighter to start the stove. Communication with the property management is impeccable, free breakfast at a nearby cafe is a nice touch (no eggs though, for someone who doesn't eat cheese or bread it's basically olives, cucumber, and grapes ;D). WiFi was very spotty on my laptop all evening, so it's good that I only stayed 1 day. So you decide for yourself if this would work for you ;)
