The appartement is nice and Güven was a great host. We didn't see his brother Güner because he runs Instanberry, the tourist office around the corner. Upon arrival Güven showed us the appartement, told us where to find everything and left us to discover the city. The appartement is very clean and has all the basics you need for a citytrip. When we wanted to stay an extra night, Güven arranged it for us immediately. I would highly recommend the place if you want to stay in an affordable, basic and clean appartement in Istanbul's charming neighbourhoud Beyoğlu.
