Staying at Fir's place was great. Check-in was simple with his clear instructions. As others have said, the location is super convenient. You are walking distance from little italy, gaslamp, and balboa park.
I was lucky enough to find a parking spot across the street that appeared to be indefinitely free, but there was a good amount of metered spots all around.
The bed was large with ample space for two people. The space was clean and clearly well maintained. If you are looking to stay close to the areas I mentioned then this is an excellent spot.
