We had a great time in Bilbao. The apartment was spottlesly clean, well provided and super central, so the places to go out are literally down the stairs. Jesu & Irene were great hosts and super helpful, with tips, information and advice over activities and anything we could possibly need. Really excellent!
Only thing: the location is central and this means it is a bit noisy in the nights. Either be prepared to party like the Spaniards or sleep through the noise.
