This is a nice place to stay with a great location only 1/2 mile from the Convention Center and one block from the middle of the Gaslamp district. The place is in a historic building and is clean, comfortable, and delightfully decorated. I enjoyed my stay.
The level of noise from the street and restaurants did not bother me, perhaps because I live in a city and am used to a certain amount of nighttime noise. I slept just fine. If you are accustomed to very quiet nights, please be aware that there is noise and plan accordingly.
Overall, I highly recommend.
