Formerly a European style pension, the Adelaide provides a good combination of low-cost and comfort near Union Square. This hostel has a nice mix of dorms and private rooms catering to backpackers, budget business and leisure travelers, and families. Some rooms are configured like traditional hotel rooms and others are innovative hostel dorm rooms with custom built beds. We’ve heard the breakfast is excellent, perhaps because the Adelaide is catering to a wide variety of travelers and tastes.
