Family-Friendly Listing Identification

Let me walk you through how I'd design a family-friendly listing identification system for a vacation rental marketplace. I'll go stage by stage — business and ML objectives, high-level design, data and feature strategy, embeddings, pipeline architecture including modeling and training details, infrastructure, evaluation, and robustness. This is a problem that touches a really high-value user segment — families represent 30 to 40% of bookings and have very specific, non-negotiable needs. Getting this wrong doesn't just mean a suboptimal recommendation; it means a family with young children showing up to a property with an unfenced pool or steep open staircases, and that's a safety and trust disaster.
