Location- convenient and walkable to the convention center, and waterfront area, and even further if you are a walker. Additionally, the trolley/ train was close enough to hop on to visit Old Town.
The place was clean- 2 bedrooms and 1 bath with a foldout sofa. My bed was comfy enough but the bedroom did not have a bedside table while the other room may have had one and this room did not have a mirror. The unit was clean and fit our needs to crash in the evening after a conference.
If we had been staying longer for pleasure please note there isn't really an outdoor area to hang out in that is nice although there are some chairs outside if you wanted to sit. The unit is in a courtyard behind businesses in the nightlife area and can be loud (not anyone's fault but just an FYI for those future guests). The walls are thin and one night heard neighbors in my bedroom that sounded like they were in there with me (a noise machine and exhausted took care of it and the owners kindly provided disposable ear plugs).
The unit also had coffee, tea, and bath products which were appreciated. If you are looking for a unit close to the nightlife of the Gaslamp this works, if you are looking for a place to crash after a convention, this could be it if you are a heavy sleeper and are looking for a unit with a kitchen. As far as safety- I read reviews about the Gaslamp and this unit's location was fine. I did not feel unsafe getting in the front gate at any point.
