Accommodation 2 nights in April

Holas a todos! 
I'm looking for a double room for 2 nights (Tues 21st & Wed 22nd April). I'll be in Barcelona with a friend for a concert. We're not looking for a freebie but hostel/air bnb prices are extortionate! We are both responsible & respectful guests. We'll be out exploring more than in your space & we have an early flight back to Ireland on Thursday 23rd. Gracias de antemano
