First of all, the hosts are great! They provide you quick response to all your questions and a lot of helpful information (transfer from the airport, nearby attractions and facilities etc).
The check in procedure is very easy and fast, the check out, also.
The place was clean, provided with all utilities that you need during your staying there, including a coffee machine.
I certainly recommend this location for anyone who wants to be sure they make a safe choice regarding accommodation and they'll enjoy exclusively the beauty of Vienna!
