Not fancy, but clean and comfortable room in a small apartment in a fantastic location if you want to be near the Gaslamp District, Little Italy, and the San Diego waterfront. You're at one end of Little Italy, 10-minute walk to the waterfront and Maritime Museum, and close to many great restaurants, including two organic ones, Cafe Gratitude (vegan and lost of raw), and Parakeet Cafe. There are tons of electric scooters around that you can ride if you download the scooter's app to your smart phone; it's a fun and cheap way to get around, about $5 per half hour.
We had a short delay upon arrival when the host left his car parked in the parking space, which was a pain since we didn't know whose car it was, didn't have cell service in the basement parking garage and had to walk outside of the garage to get service, then were told it would be 20 minutes before the car would be moved once we contacted the host. After 12 hours of travel and arriving at 1 am our time, that was not what we wanted to hear. Fortunately it only took 5 minutes to get the space freed up, but I would request that the host make sure that doesn't happen on your stay.
The shower valve makes a very loud vibrating noise which will definitely wake anyone sleeping, and probably annoys the neighbors. It didn't bother us, but be aware.
In mid-January the room got cool enough at night a couple of times to warrant some heat. The through-the-wall AC/heater made a loud whining noise for about the first 5 minutes it ran and the fan overall was very loud, but once the room warmed up we were able to turn it off for the night, so no big deal. However, this may be a major pain in the summer when AC is needed, so it should be fixed.
The bed and linens were polyester and not fancy, but comfortable. They reeked of chemical detergents though, so if you care about that you might want to ask the host to use an unscented natural detergent.
The room only had one dim lamp, so the room was gloomy. That could be easily rectified.
Overall, worth the money, but with a few tweaks this could be a much nicer stay.
