The communication with Mario is very easy he guided me all through out from check in up to the check out. He’s very accommodating and the place is near by to the station just a 2 to 3 mins walk Metro Keplarplatz around the areas there are restaurant and shops. The place is clean with complete appliances that you can use. You can also cook your own food in the kitchen. Overall we have very nice stay at Marios place. If you are looking for a place to stay in Vienna this is the place to be. Thanks Mario. I will surely come back 😉
