Our four person (two under two) family had a lovely time here. The crib was great for our infant. And the high chair and various toys were great for our toddler. As was the small fenced in back yard with grass.
The rooms were quiet and clean. And there were plenty of linens (towels, sheets, etc.) available. The neighborhood is quiet, which was nice for our kids. The shades don't really do much to stop light, sadly, so we were up shortly after sun up, but we would have been up anyway (again, two under two).
There's a Vons and Trader Joe's three blocks away, so that was super convenient for dinner planning. The kitchen is fully functional and has eveything you'd need for cooking standard meals. The hosts provided some fresh fruit and a couple bottles of water upon arrival, which was a nice touch. Be advised, though, that outside of that food, the kitchen is bare so you'll need to stock up at the nearby supermarket if you plan to cook.
Off-street parking was easy. Wi Fi was easy. The place is wired with multiple TVs (though we never used them). You're about a mile from Crystal Pier and Mission Bay, so it didn't work for us for walking (small kids). But, it was only a 5-min car ride to both locations and we had no trouble finding parking. All things considered, it was a good time.
