This cheery apartment building-cum-hotel is the welcome newcomer on an old block. Plugged into the upmarket Charlottenburg area, Otto experienced a recent face lift at the hands of Swedish designer Lars Bork, who brightened the space with healthy splashes of blue, magenta, green and black colors to achieve a contemporary chic look.

It’s easy to tell why young professionals favor the establishment, from its faultless service to its immediate accessibility. The 45 rooms take many incarnations (standard, comfort, studio or suite with a private rooftop sundeck), but each comes equipped with bottles of Aveda products in bathrooms, flatscreen TVs and wi-fi. Organic produce and weekly changing delicacies—such as Alsatian meat and cheese platters—greet guests at the very minimalist, very clean breakfast nook, as does the super fair checkout price of 80-120 Euros per night.
