Qahar is really reactive and we have been welcomed by Eyup who has been amazing: he welcomed us at almost 22h, took time to give us a map and show us the different locations we should really visit. Both have been really nice and receptive.
The apartment is just like in the photos, we were 5 and it was large enough for all of us.
The flat is perfectly located less than 10 min away from a tram station and everything can be easily done by walking.
