It depends. Jesus is certainly as important as Mohammed to Muslims and it’s not prohibited to celebrate his birth but some would never participate simply because it’s a Christian tradition. Also the ban of images makes all the customs around Christmas a little tricky. In Turkey for example a lot of Muslims do celebrate but you won’t find nativity scenes or stuff like that there, only images of Noel Baba (“Christmas Dad” = Santa) who is modeled after Saint Nicholas but himself not a religious figure.
Jesus (Isa) features in the Quran as the prophet prior to Muhammad.
Celebrating the birth of one of God’s prophets is probably still a good thing. I’ll defer to an expert though.
Also, your landlady is probably just a nice person.

Ironic, since St Nick is Turkish.
