We stayed for a week here, everything were comfortable, we were able to regulate heating which helped in cold days. Everything looks like on pictures. Murat responded quickly if we need something.
One night our neighbors started making noise and Murat quickly came, resolved situation and even provided us free breakfast as apology.
One thing you should consider is that whole Fatih area is loud in the morning starting from 8 am. Possibly this is true for all old city.
