This spot is definitely very small, but if you aren't planning on staying home much then it shouldn't bother you. There isn't much light or ventilation in the home, but it's very centrally located so you can walk pretty much anywhere in Ocean Beach or Pacific Beach (Mission Beach was sleepier, but we visited in a very off season month).
The roof deck is a little less glamorous than it looks but it is there! Bring any sugar or milk or coffee that you want because supplies are pretty limited.
all in all, I'd stay again but only if I plan to hang out minimally in the house.
