Carla is very easy to communicate with, and it was great meeting her upon check-in. The unit itself is attached to the garage, and separate from the main house. It's spacious, clean, and comes with a large kitchen - no stove, but perfectly good for prepping breakfast/coffee/sandwiches. The unit comes with a large TV and cable, as well.
The space is perfectly positioned just outside downtown San Mateo, and only a few minutes walk from Central Park at the edge of downtown. It's also only a few minutes from a Safeway and a great little Thai restaurant in the other direction. We left our rental car parked at the place two of the days we stayed - with easy access to San Mateo and two CalTrain stops, there wasn't much of a need to move it!
