This is a great and affordable hostel within walking distance to all of the best Gaslamp restaurants, bars, and transit. It's about a 20 minute walk from train station and is convenient placed.
Word to the wise, this building is directly connected to a super loud bar that is open until 2am. Request a room far away from the face of the building if you want to get real sleep. They do offer ear plugs but no AC + open windows + bar thumping until 2am = noise beyond ear plugs.
The communal spaces are vast and I love the communal vibe. It's not the cleanest kitchen in the world but it's awesome that they have such an open space for you to cook a meal at home if needed.
