Nice, it’s working! I always forget about !important tag.
Thanks!

For others, solution was this:

.flxmap-container .gm-style .gm-style-iw div[style*='font-weight: 500'] {
    font-weight: 700 !important;
}

.adp {
    font-family: "Titillium Web", Arial, sans-serif !important;
}

Well, I won’t contact them. I wasn’t able to find out how to contact them O:) Do you think it is possible to change font?

Your fix is working, thanks.
Bold HTML description is not a problem, I’ll use inline CSS for that. Now I noticed there is a opposite problem with text when I want directions – picture here. I’ll try contact Google for solution.
Thank you again!
