The host, Bertrand, is such a nice and responsible person. His accommodation is perfect for holiday, because it is not only near to the tourist spots in Vienna, but also makes everyone of us enjoy the leisure time at night. The house is really well decorated and comfortable. I live with 3 friends of mine, and we don't feel crowded at all. The space is super big, and the host's arrangement of giving us the key is so good too.
Highly suggest any guest to his house. You'll definitely enjoy:)!
