Helen's place is perfect if you need a room in San Diego. Helen's house is close to old town by bus (5min walk+10min bus), and from there, there are a lot of other transportation (green trolley to old town, Amtrak, buses). The room is very clean and comfortable. The bathroom is shared but that was absolutely not a problem, it was very clean and there was no problem for schedule. Also Helen is very nice. She knows how to welcome people and make them comfortable. She will fully respect your privacy but will also like to talk if you want to. I strongly recommend this place, especially for the price in San Diego! The only "more" negative point is that there is no restaurant or other activities close by (easily reachable by 10min walk), if you have no car. But there is a 7-eleven that can be convenient if need of small things to eat and drink.
