Location: As for me the location is good. 300-400 m from the nearest metro station.
Cleanness: The flat was amazing clean
Hospitality: Philippe is a great host. He met us at agreed time, brought coffee for coffeemaker, told everything about flat. He was friendly and helpful.
Facilities: The beds were amazing. All household appliances were modern and new. There were all small things for cooking like oil, salt, pepper, dishes, tablets for washing machine.
It was one of the best apartment of those I stayed in. I can recommend this apartment for people which want to have a comfort and easy stay in Vienna.
