We stayed at Fir’s place for two nights and loved it!
It was really clean, spacious and exactly like described and you’ll have everything you need for the stay while in San Diego.
Because it is good located and central you can visit a few things by foot, like Little Italy.
If you don’t park your car in the garage (like we did) you’ll need to get lucky with the parking situation on the Main Street.
You can also hear the airplanes flying really low, but this didn’t bother us at all. On the other hand you probably will hear the steps of your neighbor from above, so be aware of that.
Long story short: we recommend staying at this location when visiting San Diego!
