The organisation and service was astounding. Once they add you on Whatsapp you have your 24/7 local tour guide, reception and query desk all at your fingertips. The detail is what blew me away, sending me a messages to confirm a cleaning time, updating me when my home country changed it's travel advice and asking me regularly if everything was okay. I found the staff to be friendlier and more fluent than any I had come across in my stay in Istanbul, exactly what you need when you are new to a city and it's language. They also own a charming little cafe which is a hub for you and travellers alike to mingle. The gold standard of Airbnb.
