I had a pleasant experience at David's place. He was super nice and accommodating. My room was clean and comfortable, terrace was a nice feature.. and place is conveniently located from all the main spots in Barcelona. Just a 10-15 min walk to La Rambla, La Boqueria..etc. if youre a solo traveller on a budget..i would recommend this place for sure! Just an fyi..the room didnt have a lock but i didnt feel weird about that at all. In my opinion David seemed like a kind person and the place had a good vibe so it was cool. And if it's your first time in Barcelona i highly recommend doing the City Tour!! Its guided (audio) and has a 24 hr hop on hop off feature. Loved seeing all the beautiful architecture :)
