15 days Andalucia – Valencia: any tips or suggestions?

Hi guys I’m a M22 and have planned a 15 days solo trip in Spain at the beginning of September, I’ve made some research and come out with this schedule:

– day 1: arrival in Sevilla

– days 2 and 3 : full visit of the city

Рday 4: heading to Cordoba, return to Sevilla 

– day 5 : move to Cadiz and sleep there

– day 6: from Cadiz to Malaga

– days 7 and 8: visiting Malaga

– day 9: move to Granada

– day 10: full visit of Granada

– day 11: move to Valencia

– days 12,13,14: visiting Valencia

– day 15: return back home

I’ll stay in hostels and the ones I saw are:

РSevilla: black swan hostel 

– Cadiz: casa Caracol Cadiz

– Malaga : the lights hostel

– Granada: old town hostel

– Valencia: home youth hostel

Don’t know if you would recommend me something else. Thanks for the feedback :)
