I was in Lisbon last summer and noticed a very distinct soapy, super clean smell while walking around the city. It also reminded me of my hotel bedsheets, which had the exact same scent.

I asked reception what detergent they use, but they didn’t know.

Does anyone know what causes that smell or what detergent/softener that could have been? I’d love to recreate it at home.
