Echoing what the other guests have said, Marcus is a great welcoming host. He personally greeted us as we got out of our taxi and promptly showed us the casita. He also gave us some recommendations of things to do, restaurants, etc. The location is unbeatable. It was extremely convenient to walk to the local restaurants/coffee shops/bars in the Hillcrest neighborhood. And it's very easy to catch a bus to go to Balboa Park, the Gaslamp Quarter, Downtown, and other parts of the city. We didn't have a car this trip, but if you did, there is a parking spot for you to use. Marcus checked in on us from time to time to make sure everything was to our satisfaction. He's a great communicator and is very prompt in returning our messages.
This is a small place for 1-2 people. As others have said, there is no stove (just a microwave) and the bathroom is quite small (no sink in the bathroom....you'll need to use the kitchen sink). The casita is a garage converted into a living space so as you're lying in bed, you'll see the rails of the garage door and the automatic garage door opener on the ceiling. But it is a very comfortable living area in a great location of the city. If you're just looking for a quiet, clean, friendly place to stay, this is the place!
