Esen was the best host my group have ever stayed with of all other airbnb experiences so far. He was very friendly, polite, helpful, and most especially funny. You can't go wrong with someone who loves cat so much! We arrived at around 2am and he was standing by ready to welcome us with some warm cups of Turkish tea and we knew at the moment we were about to be well taken care of. He is a type of person who you would like to share stories with, getting great insights about the city. The accomodation itself is very comfortable and perfectly located if you want to fully experience Istanbul. Nisantasi is a high - end shopping area and a bonafide suburb. If you get to the point that the old town is too crowded and touristy, Nisantasi is your place to be because from here you can easily go to Northern side of Istanbul (Ortakoy) and Istanbúl's Asian Shore where you can relax like the locals do. Istanbul's Old Town is conveniently accessible by Metro to Taksim Square, which is 5 minute walk away, or by Tram from Kabatas area, which is 10 - 15 minute walk away through a scenic route. All in all, excellent.
