You can't book on-line with frommers, but I think some will list a web site or e-mail. If not, a little search on-line will usually turn up a way to contact the hotel.

I've found a number of on-line booking agents doing these searches. Some, like inter-hotel, charge a booking fee, so be careful. At the same time, they may also offer enough of a discount on the property to offset the fee.

Hostel Levant is one in Barcelona that Frommer's likes that has very low rates. You can visit their site at http://www.hostallevante.com/eng/index.htm
