Shop recommendations in Barcelona?

Hi all! I'm visiting Barcelona soon and would like your recommendations for perfume shops to visit please. I found some but no idea if they're actually good. Would like to visit a shop with niche perfumes which aren't the most common ones if possible. Any suggestions?

I only shop with them online, but All Yours has a very nice selection!

El Corte Inglés for sure and as mentioned All Yours had an awesome selection and the staff was amazing - they let you try it all at your pace and didn't try to push any sales.

The Perfumery is a must visit. Take a look at their website to see what they carry. Their in-house brand, nBitor, is worth trying. theperfumerybarcelona.com

Carner Barcelona. 

El Corte Ingles is a department store. I visited two of their stores in Madrid. As tiagosmells pointed out, it's worth a visit.

Voila!
