A nice, clean, affordable hostel in Barrio Logan. Shanna was excellent with communication and would respond to messages in minutes. We were alone in the hostel for the first few days, but once others started to arrive it was still pleasant, and guests respected each other's privacy and belongings. The rooms are just enough space for sleeping and relaxing after a long day. The kitchen is cute but can get cramped if there are a lot of people using it. Bathrooms right off the kitchen and were clean and new, and varied in size - 2 large with shower + toilet, then some individual toilets and individual showers.
The neighborhood was relatively peaceful while we stayed there, with some people about, and sometimes bikers hanging out and listening to music at the place across the street. Overall good during the day, and fine at night, just be careful and mindful while walking at night. But do be careful walking home down National Ave/from the 12th & Imperial trolley station at night, as there are a few streets of homeless encampments between the hostel and downtown (we opted to Uber home at nights rather than walk through them, though when we did walk through we had no one mess with us).
Really close to bus lines and trolley, too, although parking is sparse if you're renting a car. Overall a nice, affordable place to stay and explore San Diego.
