The flat itself was well equipped and had everything one needed for staying a couple of days or longer.
Even with the owner’s instructions via telephone (and I had a Turkish friend with me, so it was not a language barrier problem) it was difficult to find because the house number on Airbnb is not given (only floor “Kat” and apartment “daire” number). The bedroom shown in the pictures was locked which was a bit weird so I had to sleep on the sofa or in the “office/laundry drying room” where a single bed was placed but I chose the sofa.
During check-in I wasn’t told that I had to turn off the heater or take out the trash before checking out. A day after check-out Mehmet messaged me and reproached me for not having done both. If I had known I would’ve done both. So the communication could’ve been better.
