Nothing special
This hotel does have some positive points - the room was clean, the a/c worked efficiently, there was never any problem parking, front desk staff were friendly and helpful, but there were a few negatives too. The room was very small and we (two adults, one teenager) were tripping over each other frequently, it felt very claustrophobic. The breakfast room was always very crowded, it really isn't big enough to cope with the number of people in the hotel and the breakfast itself was very average. The swimming pool is surrounded by beautiful flowers and plants, such that you can almost forget that the hotel is next to two major roads with traffic speeding past all day, but it is really cold, and there is no hot tub to warm up in.
The location, as other reviewers have noted, is very convenient for the state historic park but the hotel itself feels rather out on a limb, stuck in a strange industrial no man's land. You can walk to the state park where there are plenty of restaurants, but it is not a particularly pleasant walk. If I return to San Diego, I would probably choose a different hotel.
