Yes, warm is good, but unfortunately I have already used "warmth" in the previous sentence: Found in old houses as well as in modern apartments, terracotta tiles add to the warmth of any interior.

I'd vote for "warm" if you put it as a suggestion. Can one person submit two answers?

"Homey" and "homely" are often confused: "homey" refers to the comfortable quality of a home, and "homely" means unattractive, referring to a person. But I'm not sure "homey" is the best choice anyway, since to my mind it sounds a bit too cozy in an ordinary way. Perhaps the adjective to correspond to the noun "douceur" could be chosen according to the image the company is trying to convey in the rest of their description of the tiles. I chose smooth, which would put the emphasis on a physical quality of the tiles, but you could also take something more metaphorical (mellow, warm?) Actually, thinking it over, I think "warm" might be better than smooth!

I was wondering if I could use "homey" in some way, but the Robert & Collins directs me to the entry for "homely" which translates to "accueillant" in British English but "sans charme/ peu attrayant" in the American meaning (definitely not what I want). I am a US espeaker translating for an international audience.
