I stayed at the Man Cave for three nights for a business meeting. The unit was as advertised, clean with quirky decor. It's fairly small, but that's what I expected and it met my needs. The bed was comfortable. The unit included a closet with hangers, a medium-sized flat screen tv that I didn't use, and a small fridge in which the host had placed several bottles of water. He also left out a few candy items (M&Ms, etc) as a nice welcoming touch. The sink, toilet, and shower were all in good working order, and the water pressure and temperature were good.
The check-in process was easy. The host sent me an email a day or two before my arrival with access codes that worked just fine. Check-in was not permitted until after 4pm, but I could have arrived earlier to drop off my bags at a secure location in the building if I had wanted to.
The building location was as expected. There were a fair number of homeless around, but that seems to be true throughout downtown San Diego. I never felt threatened (though I'm a tall man). There was a Starbucks and a couple of places to eat (pizza place, diner, etc.) within a couple of blocks. Parking was an issue, but I knew that from what others had posted. I found parking about a half-mile away with no meters or restrictions, and left my car there for a couple of days since I didn't need it during my stay. I moved it to right in front of the building the night before I checked out so I could easily move my things into the car the morning of check-out. I went outside right before 8am to feed the meter ($1.25 for an hour), and left by 9am.
I had two issues with the unit that caused me to give it four stars. First, the walls and ceiling were paper thin. On Saturday night, there was a lot of noise in the staircase and hallway until at least 2am. On Sunday morning, I could clearly hear people chatting in the courtyard outside. There was no noise Sunday or Monday nights, though. Second, the shower was very cramped and the shower head unusually low -- barely shoulder-level on me. It made showering a bit of a challenge. As I said, though, the water pressure and temperature (hot) were good. Also, there was body wash and shampoo in the shower, and the host provided towels (as one would expect).
The host sent a couple of polite emails during my stay to check in and make sure I was doing ok.
