The provided check-in location was incorrect. Possibly may not have been the host's fault but the address needs to be updated. The provided address took us to a location 10 minutes walk away and it was frustrating once taken the taxi and walking around at night trying to find the property. We eventually found it by entering the address found on one of the pictures.
Property was clean and as described, Mehmet the apartment manager was helpful once we reached the location.
There were some issues with the apartment such as door handles coming off easily (bathroom and bedroom) and cigarette smells because of the ventilation or front door. In other words, neighbours smoking sometimes could be smelt in half of the apartment. No shower gel/shampoo provided as described in the listing.
The location of the property is convenient for the area close to shopping malls and main street. As a frequent visitor of Istanbul, Şişli/Nişantaşı are nice areas if you're not visiting Turkey for first time.
