Güven was helpful to arrange the taxi ride from Ataturk Airport to our appartment (140 TL). The appartment was as described, clean and quiet. Dishwasher and WIFI were working. The TV doesn't have a lot of channels you would like to watch, most of them are arabic. The entry door is massive and secured with alarm. We had a little incident in front of our appartment because there was a demonstration in the city and police attacked protesters in our neighbourhood as well. Güven promised he will insure the safety of his future guests by checking security cameras in front of the house. We always felt safe during our trip in Istanbul, but stay away from gatherings of people because the police will always break up demonstrations with water-cannons and teargas. Check travel warnings from your goverment before departure.
