I stayed a few days at the Jaz and was very happy. The record player in the room also included bluetooth, so on top of borrowed records from the reception, I was able to hear my own music in a much better way than usual. The interior is brand new and the reception was very helpful through their chat app on the room computer to bring amenities that were not already in the room. I could probably also just have called. Good balance between overloading the room with stuff that most people do not need and still make it available. The restaurant was good with a fair selection of wines, also by the glass. The same goes for the rooftop bar that is a must visit, even if you are not staying at the hotel. The service was very attentive all over the hotel. The good bed took up most of my in-tune room and there was no table to work at, but was as advertised, so not a problem as such. I do prefer the record player over a plain desk any day :-) The hotel is close to the Mariahilfer Strasse which is a main shopping street in Vienna and there are many eating and drinking choices in the vicinity as well. I will definitely keep the Jaz on my list of preferred hotels in Vienna.
