We had a nice stay at Sea La Vie while attending festivities around our son's Marine graduation. It was very easy to get to and from the apartment to the airport and MCRD, as well as to downtown. The apartment had what we needed for a brief stay, though we didn't do much beyond sleep there.
Something to be aware of is that the house above the apartment is occupied, so if it bothers you to hear people walking across the room above or running water you're definitely going to notice it. Others have noted this in reviews as well. It didn't impact us much.
