Communication was good, walking with luggage to the destination is super challenging. At 1st glance the area comes across intimidating due to heavy road construction however don't be fooled super good small restaurants in the area and perfectly located to Taksim Square.
As the unit is self catering I found that the apartment was very limited in accessories example no ironing board no washing line / rack very limited utensils if you wanted to prepare something for your self. The AC unit was a bit noisy.
Although I would not say there were tangible service failures I do think the unit is over priced comparing with other big cities in Türkeye.
