Mariano's place was great. I went to Vienna for short a short weekend to visit some friends. The place is very close to the subway which enables you to get anywhere in the city. Also there is a supermakert at the metro station in case you need anything.
The place itself is located in a garden compound with lots of green. The room has a small balcony with nice views to relax. Also, it was spotless clean and had everything I needed.
Mariano is a very friendly host and I can only recommend staying here. For my next stay in Vienna I already know where to go!
