The Mudville Flats Boutique Hotel was a fantastic place to stay for my convention! Communication with the host was superb. The apartment was really charming - it felt like the sort of place that I would be happy living in. It was near enough to the Convention Center that I could easily walk back and forth. It's perhaps worth noting that that entire region of San Diego can feel a little bit rough at night, so Uber/Lyft/taxi may be worthwhile if you're walking alone after dark. That's not a knock on the hotel itself, though.
