Sheraton San Diego Resort
beautiful property, right at the marina and the Bay with great views

Wyndham San Diego Bayside
Room was smelling of something every time we entered. We would open the balcony door and that would make it go away. Balcony was really enjoyable. The location was perfect to enjoy the views, walking distance to all attractions. Other than smell, everything was good.

Best Western Seven Seas
There was a large centipede like bug on our bathroom wall on arrival. Room was run down and the plumbing sounded like somebody was drilling through a concrete wall with a hammer drill whenever any of the adjacent rooms were showering.
