Karen's place is right in the heart of Old Town San Diego. Complete with parking space - it's a great little place to stay. We were allowed to check in early, which was really nice. The beds were comfortable and we were pleasantly surprised with a mini fridge, which we used. It was nice being able to walk around Old Town without having to stress about parking. Karen is super friendly and very helpful. I tried reaching out to her one night for something non urgent and didn't get a response until the next morning, but aside from that, communication was great. The living area is fairly spacious, it's definitely a good sized space for two people, but can really only comfortably accommodate three people at most. There is a bit of street noise, but I didn't notice any after around 10pm though. The bathroom is pretty small and the sink is outside of it, shared with the kitchenette, but there is a super cute patio and tons of information on sights to see. We had a nice stay overall.
