Staying in Christoph's flat was en excellent experience. He contacted quickly and arranged the check in, which happened swiftly. Every detail in the flat was shown, and the place is very good. The flat is beautiful and correspond to the pictures -- it is comfortable, has three large windows that allow aeration, and is located in a quiet small road, even though it is VERY close to main attractions in Vienna, in a good neighborhood. It is also 4 min walk from the underground. The house is comfortable, the fittings of the kitchen and bathroom modern. The flat was very clean, and the bed linen and towels good, clean and well presented. Cristoph was always around and making sure that I had everything I needed. I really would stay again and recommend Cristoph's flat for anyone in AirBNB.
