Great place overall, good aircon in hot vienese summers, cleand and nice bathrooms! loved the bathroom glass that has a bluetooth speaker so you can take a shower and listen to some music. Its quiet and has opaque curtains so the sun won't bother you! Only down side was the fact that the luggage lockers were broken (I booked 40 days in advance and they did indicate to use the ones from the train station, but I don't speak german) and still not fixed when i arrived. I had to carry luggage under the very hot summer and this soured our first day. Everything else was perfect.
