I had a great time staying at Suha's!! The condo is in a prime location in regards to night life, restaurants and public transportation. If you are attending a convention it's about a 6 minute walk to the convention center.
The neighborhood is busy but I felt very safe. It does get a bit noisy starting at about 11am all the way to 3am. It is literally in the middle of the party so if you have issues with noise I would bring earplugs.
The condo was very clean and the pictures are accurate. Unless you plan to venture out of gas lamp you really don't need a car. The airport is about a 12 minute uber/lyft/taxi ride to and from the condo. I didn't contact Suha very much as the checkin process was simple and the condo was as expected. But when we did communicate she was responded quickly.
All in all I would say that this has been my best Airbnb experience! I miss sunny San Diego already!
