Excellent experience! The house is very clean, neighborhood felt safe and was very quiet, great location. Appreciated little touches like the laminated instructions over pertinent places in the house. The beds are very comfortable. There were plates (3 large, 3 small - might need to bring more if you have a larger group), cups, utensils and other kitchen items. Brita water pitcher in fridge. Host was extremely responsive. Lots of room for 3 adults, 2 babies. Might be a little cozy if you have too many more adults (ideal number would probably be 5-6 adults, though there's bed/table space for more).
Entrance was slightly difficult to find, but we were provided very thorough directions and eventually found the house after reexamining the map carefully. Parking is right in front of the house. There is one flight of stairs you need to climb to get to the entrance if you use the parking in front. It seems like if you park on the street above the house there may not be stairs to get to the entrance.
The only downside is that the common area was pretty stuffy/warm during the day, but we did visit during the hottest time of year. There is an AC unit in each room, which helped a lot. There are many fans in the common area, but because of the weather, they were circulating hot air. If you look at other Air BnB's in SD though, central AC is actually very uncommon and having an AC in each room like this Air BnB is somewhat rare. So we made the most of the situation by trying to be out during the day and opening windows + turning the fans on when we were in. This is probably not a problem for the majority of the year though as SD is usually very temperate.
Overall, one of the best Air BnB experiences I've had. Definitely recommend staying here and would absolutely stay here again.
