My boyfriend and I enjoyed staying at Nicholas's apartment during our trip to San Francisco. We weren't able to meet him or Serena but the check in/out process was smooth. Everything was super clean and comfortable. We took public transit our whole time there- the BART station is 15-20 minutes away by walking. At non-rush hours the trains don't come as often, so make sure to budget a bit of extra time. Overall, though, we had a wonderful stay!
