My 5 week stay at Royal 61 Kadikoy Suit was simply wonderful. The room is clean and spacious with a comfortable king sized bed and full length sofa (three people could comfortably stay here if necessary), a massive fridge and accompanying kitchenette, air conditioning and plenty of natural sunlight through the many windows and large bathroom.
It is extremely quiet, located on the 4th floor, and it is easy to forget you are in the bustling centre of Kadikoy, surrounded by restaurants, with at least half a dozen supermarkets less than 5 minutes walk away in all directions and the bus interchange, metro and ferries all within 5-7 minutes stroll. The location is superb for local convenience and transport.
The ground floor office is staffed from 11am to 7pm and there is a private side entrance for all hours access. Washing machines and driers are available for use in the basement, accessed through the ground floor office during working hours. There is an elevator available, although you will have to walk up a single flight of stairs to access it. If you have a lot of luggage, don't worry though, because Mr Beyazit and his staff (it is a family run business) will be on hand to help you. They are all most wonderfully kind, polite and helpful people.
In fact, I have travelled across Europe (Germany, Italy, France, Spain, Hungary, Turkey), Asia (South Korea, Japan, Malaysia, Taiwan), and the US and have stayed in countless Airbnb accommodations and I can say definitively that Mr Beyazit's hospitality, kindness and professionalism tops them all. He is incredibly prompt with responses via WhatsApp, has a solution to every small dilemma (even those that are completely unrelated to the accommodation) and truly goes above and beyond to make sure you enjoy your stay.
I cannot say enough good things about my stay here and this Airbnb Host. I will definitely be returning here for my future visits to Istanbul.
