The house is clean, modern and perfectly equipped. You have a nice view from all the windows and you can reach the centre of the city in 10 minutes by tram. The furnitures look like they were just brought from the store. The beds and the sofa are comfortable. There are fresh towels for 4/5 people and also the bathroom and toilet room are great. (Toilet and shower are in two different rooms, which is a really clever choice in my opinion).
Sun is a great host and took the time to come back when we accidentally locked ourselves outside the house, overall a great experience, I am going to come back here for sure when I'll visit Vienna in the future. Thank Sun!
