Excellent location! A 20 second walk from Galata Tower tourist madness, but on the quaintest, quietest street in the Galata area. It's a short climb (quite steep) to Tophane station, and in the other direction to Sistane, the major public transport stations.
Unit looks into a private courtyard, very green and lovely, like a sanctuary from the hectic Istanbul. Bedroom is comfortable and cozy, kitchen is very well stocked with an oven, state of the art dishwasher and top of the line German appliances. Bathroom is spacious and comfortable with a window looking out. The whole unit is exceptionally clean. It was a comfortable stay.
Gizem organised my stay and was wonderful - she was on call all the time for any questions. I couldn't have asked for better communication really!
One thing to note - I stayed here end July/early August - weather is not terribly hot yet, but I sleep with AC at night during summer... The AC units have a habit of turning off as they like. They are central AC units which are weak, so when they turn off you need to wait about 15 mins to hope they turn on again. This can be annoying if you are stressed by AC like me.
EXCELLENT value for money.
