The exterior may look old and historic, but the room was quite modern, very spacious and with a very high ceiling. Wifi coverage was great, the bed stands had power outlets, the bathroom was very clean and well designed and had everything you'd need. The gym was relatively well equipped by hotel standards and well maintained, as were the saunas. The lobby and other amenities were also quite nice, with two large rooms that served as a kind of library. It almost felt like living in a palace, except with a modern room. I just wish I had been staying longer! The only minor complaint was that housekeeping didn't respect the do not disturb sign on two occasions. Transportation was also super convenient since the U3 U-Bahn station was right outside the front door of the hotel.
