Ulas was super responsive and helpful throughout my stay. He was very respectful of my parents and took great care of us offering us water on the first day as well as local treats such as baklava from time to time. He even offered to book a taxi to get to the airport on the final day.
On the arrival day, he stayed up late to allow us to check in. One thing I would mention there is to agree beforehand how the key handing over process would work since when I got there my mobile data did not work which meant i could not initially contact Ulas.
The apartment from the inside was exactly as described. It was nice and clean. The only concern about the building I would raise is that the stairs dont have handrails on them so they are a bit dangerous especially for young or old people. There is also no lift.
The location is great for exploring the tourist spots in Istanbul and there is a tram station very close by.
Thanks for everything Ulas.
