The location in Istanbul is superb, it is a lovely area with countless options for lunch and dinner as well as shopping. A supermarket is 50m around the corner. The metro station is about 15min walking, from which it takes another 15min to get to the old centre. We selected the AirBnB for the quality of the WiFi as we had to work remotely from here for a week. WiFi was fast indeed, we could hold video calls on two laptops simultaneously. Average speed was 50Mbps download, 4.5Mbps upload. The apartment is spacious with a proper table to work from. It also comes with a fully equipped kitchen with dishwasher and washing machine. Esra is lovely and very quick with responding.
The apartment decoration is rather basic, but functional. Downside was a rather musty smell from the bathroom, as it doesnt really have a proper window to air the room. The bed was ok, but not the newest anymore. We could hear the neighbors at night, having some friends over until late night or walking the staircase. I read many reviews about apartments in Istanbul and believe this is common as many buildings are rather old with thin walls.
Overall good value for budget.
