Juan is VERY kind, hospitable, social and friendly. We stayed for 5 nights, and we felt like home. He made us BBQ just because, and we had wonderful evenings on the terrace with him. We saw guitars in the living room and he took time to play it for us (spanish guitar), and answer all our burning questions! :) we spent much of our evenings together, either in the flat or walking all around town. It was definitely the best airbnb experience so far, really recommend it! The flat is in the heart of the city, with metro stations very close by (1-3min walk).
Bed was super comfy, we slept like babies. We could use washing machine for free, as well as any other amenities in the house (terrace, kitchen, etc.). There are 2 toilets and 2 showers, which is very useful as well.
Our experience in Barcelona was definitely elevated greatly by staying in Juan's home :)
