Hi Everyone!

My friend and I are visiting Madrid, Barcelona and maybe 1 other city in late June. Do you think it's necessary to find a hostel that has air conditioning? I've found some places I'm interested in that are inexpensive and have good ratings, but no mention of A/C:

Madrid: Hostal Las Murallas
Barcelona: Habana Home

Any ideas about these 2 places or other suggestions?

Thanks!!!
