Srsly the best Airbnb experience ever! Craig and Inga are wonderful, and will interact with you as much or as little as you want. Craig responded immediately to texts whenever we had any questions. Warning: a dog does live on the premises (but not in the airbnb apartment and you'll never see or hear her if you don't want to; we all like dogs so we wanted to play with her and Craig let us, she's very sweet), but if you're allergic or hate dogs this might not be the best place for you.
The place felt very safe. The manager Craig lives in the house but in a completely separate apartment on the first floor. The airbnb is its own apartment on the second and third floors, and there's a door with a lock and chain separating it from the rest of the house. So you don't have to worry about anyone coming in or anything like that. It's 100% secure and separate.
House is old but very clean and bathrooms and kitchen have been updated nicely and everything worked perfectly. Steps leading up to the house are a bit steep and uneven so be careful with that, especially while carrying luggage (Craig offered to help bring things in and up to our rooms). The living room has a door and a pullout sofa bed, so could be used as another bedroom if needed.
Amenities and decor were great (loved the antiques displayed in the first floor lobby and dining/conference room). Sheets and towels were soft and good quality (and I'm picky about such things, actually brought my own just in case but didn't need to use them). Eating on the outdoor deck was lovely, there's both a gas and charcoal grill, and we got a free fireworks show every night we were there! (You can see the fireworks from Sea World.)
The neighborhood felt relatively safe. Gaslamp district and convention center are a quick 6 minute, $10-$15 uber away, not walking distance IMO (and there are sketchy areas with lots of homeless along the way so I wouldn't recommend walking there). Plenty of street parking, we had 2 cars and never had a problem finding parking right in front of the house.
So overall our stay was great, loved the place, and hope we can book it again the next time we're in town!
