Göksu was right on time when we arrived in Berlin and she nicely and quickly gave us the keys of the flat which was very convenient as we didn't need extra information about Berlin (we've already been there before). The flat is nice and clean and the balcony is great. The thing is that the bed is not really comfortable (thin mattress) which is a shame as we would have liked to get some comfy rest after a day hitting the town + there are no shutters, it was very hot in Berlin and we were awaken at 6.45 am because of the sun heating our faces. But the flat is located close to a metro station and you can reach the center of the city quickly :)
