We loved our time in San Diego! Not only was this unit spacious and full of really nice details (super nice towels and sheets, really comfy beds) but the neighborhood was awesome. Walkable to shops, restaurants, coffee, and a great little park with swings that was only a five minute stroll away. It was the perfect place for families. Highly recommend and we'll book here again if we ever visit SD in the future.
Only recommendation for other people traveling with littles: bring a small, clip-on, battery-operated fan. Not only is it great for the stroller when you're somewhere super hot (like the zoo and Balboa Park) but it was great to aim at the pack 'n play as the back bedrooms get rather hot, even at night.
