Welcome to Hostel on 3rd! We are a very young hostel in a beautifully renovated historic building, located in the heart of San Diego’s Gaslamp district. Looking for a night out in the town? We are one short block from the vibrant nightlife. Looking for a quiet night of sleep? Our building is located in a prime residential block, assuring a restful night. We are a few short blocks from the downtown convention center, and a short way from the zoo, museums, beaches and all that the beautiful city of San Diego has to offer!
