Choose Otto for 1 night stay because of good rating and was not disappointed. At arrival got upgrade to studio which was quite big room with kitchenette. Hotel is contemporary design, simple but with many nice touches and perfectly clean. Included are lot of complimentary amenities: well functioning wi-fi, afternoon tee in lounge, bottle of water. We cannot comply about noise, but hauling luggage by stairs was some disappointment (lift stops between floors). Room was not too hot, but with big radiator (good for drying washed clothes of our kid). Shower only. Excellent breakfast buffet worth EUR 15.
