Edwin's Vintage Appartment is one of the best Air BnB Places I have ever stayed at. Everything makes you feel at home, especially the vintage decoration, indirect lighting, that you have speakers to connect your phone to, a heating if it gets too cold and a decent kitchen where you can find eveything you would need for basic cooking or a nice breakfast. The bed is big enough for 2 people to sleep comfortably and has a really good matress.
And about other ratings: It is not noisy at all or more correctly maybe: It will be hard to find a place quiter than this in central Barcelona.
The location also is really good: Metro, supermarket, restaurants - everything is literally around the corner and the street itself looks really nice. You're not in a touristy area but you can easily walk there within 5-10 minutes.
I'm very happy to have stayed at Edwins appartment, he was friendly and welcoming and it would definately be my first choice when I come back to Barcelona.
