In terms of being a base in the city this is great but the place has its drawbacks. Ideal for easy access to the main station. Very clean and compact room, hence the cocoon, perhaps not great if there are two of you, but nice look and with all facilities. Good walk in shower and sink (in the bedroom). Air conditioning in the room was good. Lighting in the room was truly bizarre and rather useless. No ceiling light, wardrobe area in complete darkness so impossible to see into your suitcase, but shower room was glaring with light. Reading lights over the bed only useful if you are lying down. The noise from the floor above was deafening so difficult to get a good night sleep. The guy on reception was very brusque, didn't feel confident I could have gone there if there was a problem. The area around Karlsplatz is quite dodgy at night so didn't feel that safe on my own. Would stay there again if no alternative.
