Garen was an outstanding host helping in all regards. When we arrived a lot of cold water (and some fruits and chocolates) was waiting for us in the fridge which is a huge deal in Istanbul summertime. The house was nice and clean and every room had its own ventilator which was more than handy. Location wise it could not have been better as the house is just a few minutes far from Taksim square but much more quite. Garen even helped us to find a driver who took our group of 8 to the Black See even though I asked him only a few hours before the planned journey. Recommended.
