Alba and Carlos are great and very welcoming hosts (thanks for sweets and cava!). They showed us everything around and answered all our questions, gave helpful tips.
Flat has everything we needed , quiet and comfortable to sleep . PS: roof terrace looks amazing (but weather around NYE was quite cold so we couldn't enjoy it in the evening).
It is very easy to get to the center and even easier to get to Camp Nou ;)
We enjoyed our stay in Barcelona and communication with Alba and Carlos and would definitely recommend their apartment.
