Where can one find deals for cheap Barcelona hotels?

* Book in advance. The best way to get a cheap hotel in Barcelona is to book as far in advance as possible. This is especially important for peak travel times, such as summer and public holidays.

* Stay in a hostel or guesthouse. Hostels and guesthouses are a great option for budget travelers. They're usually much cheaper than hotels, and they often offer shared kitchens and other amenities.

* Look for discounts and promotions. Many hotels offer discounts and promotions, such as AAA discounts, senior citizen discounts, and military discounts. Be sure to ask about any discounts you may be eligible for.

* Book through a third-party website. Third-party websites like Hotels.com and Expedia often have discounts on hotels in Barcelona. Be sure to compare prices before booking.

* Consider staying in a less popular area. Hotels in less popular areas of Barcelona are often cheaper than hotels in the city center. If you're willing to stay a little further away from the action, you can save a lot of money.
