Everything was fine, can’t say much. The apartment was clean and beautiful. All the commodities were fine. The spa/workout section wasn’t perfect but as a replacement for some time works ok. (There was a broken machine, but I hope now it’s fixed). The communication was also good.
The only problem was the positioning of the appartement, it was very far from everything. Gladly there is a shopping mall “212” 15 min away by feet. Istanbul mall is basically unreachable simply walking, I tried to adventure myself - it took me around 3 hours. By taxi it takes anywhere from 5 to 20 minutes on a busy day. Should I say busy time, because the city is always full of cars and trafic issues are impossible to avoid.
My usual trip to the center of Istanbul (Civahir mall/Taksim) would take around 40 minutes, except at night from 11PM till 6AM it would be around 20/25 minutes. The cost - around 150/200 Lira one way. So do your math before planning the trip. I’ve spent around 350 euros on taxi.
