Our family stayed at the Leo by Sonder for 3 nights, 4 days.
Location: A decent distance between petco park/gaslamp so there's enough parking on the street. Check the meters because the price can be different across the street. One of the nights was difficult to park because of the Padres game. People parked near this place and walked.
Cleanliness: we found things that weren't a big deal for us, but still worth mentioning. Husband and I caught several fruit flies throughout our stay and still saw a few before we left. Not sure what Sonder can do about it, but just be aware. One of the bedsheets had stains (clean, but just stained). We took a vaccum mop because we have kids so that helped us keep the place clean.
Items provided: They provided laundry detergent which was super awesome since we didnt want to buy a whole pack. Shampoo was provided but I would bring my own next time. Dish detergent, dishwasher, broom/dustpan, icetray, extra bedding (thank goodness), extra towels were all available. These are miscellaneous items that were not mentioned, so it's something good to know.
Close places: Smart and final is literally across the place for your grocery needs and a few walkable bars and restaurants.
Overall, the place was good for us to travel to different SD landmarks. The place was quiet and provided enough for our family of 4 to enjoy.
