I don't see this as a boundary violation, infact, she seems to be expressing that she trusts you enough to invite you over to her home. Also she wants you to have a chance to see her more 'personal' side. Often in peoples homes they have art on the walls that they like, pictures of family and stories that tell about their life. No reason to be overly concerned and I would assume that since she invited you over, she wants you to come. Sounds like it could be interesting and new, maybe you should check it out and report back.
