The Orion is a charming, family-friendly hotel offering clean, spacious rooms (most with kitchens) at affordable rates. The location is on one of Vinohrady's prettiest streets, with plenty of restaurants and cafes within easy walking distance. The rooms are on the plain side, but certainly comfortable for a short stay.  Suite 64 offers its own rooftop terrace and garden, but book ahead since it's often reserved.
