Pre-chekin communication was really bad. Sladan hasn't been answering to my messages via Airbnb so I almost cancelled the reservation and asked Airbnb to step-in. After contacting him via Whatsup, he finally answered. I was worried because I was with my pregnant wife and we were already on the airport boarding to our flight and we didn't heared from him. At that point I thought we're going to be played out. Fortunatelly, things played out well and his mother greeted us at his place. We were a bit late, because some difficulties at the airport and we also missed the train from Vienna airport to the city.
We had a great stay at Sladjan's place. It is really nice and it's well equiped. Area is peacful and on a great location. It is close to the tram that takes you directly to the city. Nearby you have Eurospar, pharmacy, etc. The bed is great and we had an awesome sleep.
I'd recommend his place, but he'll need to work on his communication skills.
