good for the young and hip
I stayed here the first day I arrived in Tucson in September 2003. I was looking for a hostel, but the Roadrunner (the only real hostel in town) was limiting its stays to two weeks (it wasn't made clear why).
All rooms are on the second floor, accessible via a staircase. All rooms consist of an old-style radio, a bed, a telephone and a small bathroom. There are no televisions in any rooms, which is intentional by the owners to maintain the heyday charm (1920's) of the hotel.
Hostel rooms run $20 per night plus a key deposit, and contain a single bunk bed, which means you split it with one other person, but that person probably won't come in the off-season.
Hotel Congress is the coolest hotel in Tucson. The lobby has a beautiful, 1920's-era decor, with a bar (no beer on tap), a cafe open most days and weekend nights and a barber shop.
There's also the club. Club Congress hosts well-known, national acts but also serves as a dance club when no one is performing. The small Tap Room inside the club also offers a minimal selection of beers on tap, but provides a shelter from the club.
The club can become problematic to hotel guests at night. All rooms are on the second floor, and hostel rooms are right above the club. The lobby bar also becomes crowded on the weekend nights and allows smoking after 9pm.
Hotel Congress is in a great location though. If you arrive by Greyhound or Amtrak, it is right across the street from both depots (although Greyhound will be temporarily moved for the next couple of years due to construction). Congress Street, the hotel's namesake, is one of Tucson's two bar streets. Both sides are lined with bars, clubs and restaurants for about four blocks. The other bar street, Fourth Avenue, is a short walk through a railroad underpass about two blocks from the hotel. This area is a little more college-oriented, but is also much more active during the day with eclectic shops, many more restaurants and the occassional street performers.
Unique Quality: An excellent location, a unique atmosphere and an authentic decor.
