The place was nice and spacious and it's conveniently located near a tram stop but I would not recommend staying here in winter because the water and room heaters were both not working. The water was literally painful to use because it was so cold and we had to sleep with extra socks and sweaters because there was no room heating. We actually went a day without bathing which we were all uncomfortable with. We tried emailing our host that night and he immediately replied back, unfortunately his instructions did not make sense (like to look for particular symbols on the boiler display, when the boiler didn't even have a display). So we called the 24-hour hotline the next morning despite not having a local sim and the operator tried giving us instructions which we couldn't follow, upon which they admitted that they had multiple properties and weren't sure what kind of boiler our specific property had. We gave up trying to figure out the heaters after the call since we had already spent most of our only morning in Vienna trying to fix it. We were all thankful that we were leaving the place one night early (we paid for two nights but ended up leaving before the second night) even though we wanted more time in Vienna.
