Like many have said, the apartment is in an unassuming building but is very modern, airy and well-furnished. Appliances all work well and cleaning tablets were plentiful. It was a great spot to relax and work from with Redwood City cafes and restaurants just a few minutes' walk away and a nice neighborhood to stroll through once you go a block or two away from the tracks (it's true that you learn quickly to tune out the Caltrain).
The parking spot requires you to approach a steep driveway so approach carefully, luckily it's a fairly quiet street so backing out onto the street was also rarely an issue. Would definitely book again if I needed to stay in the area.
