Quick response
I live in Japan and therefore busy work and time difference made it difficult but our dear host accommodated at his best effort! I was still texting him at the airport which would be his day time and when I arrived at the airport at 6 am he responded really quickly whether or not I could check in early. I wonder if he sleeps at all! But it examplifies that he really makes an effort to attend his guests and it can be felt across the internet with his actions. I thank him for that!
Cleanness
I am quite picky about bathroom and toilet but I could take showers without feeling too disgusted! That is rare with me and again I can gauarantee that the place is really tidy and nicely cleaned.
Location
I bought a 3 day Vienna pass which includes transportation and I hardly used the metro because it is so close to downtown where all the restaurants and museums are. It is a lovely stroll after a big meal too! Plus it is 10 mins away from CAT (city airport train 16 mins to the airport direct). The location cannot be any better. And the cost performance was beyond expectation.
All in all, I hope I made it convincing enough that this place is a good pick and you will not regret your choice if I were you!
