The penthouse at Sam's place is lovely for a couple or a group of close friends, and is perfect for a stay in San Diego if you are planning on being close to the airport and downtown area such as the Gaslamp District, Balboa Park, etc. The penthouse suite felt much bigger than I was expecting, even based on the pictures, and I appreciated how well thought out the check-in process was - all directions to get to and into the house was included, from parking instructions to door codes to internet connectivity. I definitely liked not having to connect with someone for our stay, as it meant I didn't have to worry about checking in at a specific time and could work it conveniently into my travel plans.
Another thing I appreciated was that policies were stated clearly up front (such as not having full kitchen usage and "quiet hours" starting at 10pm), so we planned accordingly. It also ensured that I was able to find the perfect place for my stay, which required that we be up early on both mornings and thus needed to get to bed by around 10:00pm-11:00pm.
The common areas are enormously spacious, and great for (as examples) ordering in take-out for a cozy dinner in, or waking up to watch a soccer game on the TV.
The suite itself was lovely - I loved the bathroom space, which included a jacuzzi tub, and all of the light switches and controls for the fan and blinds were neatly and helpfully labeled along with instructions. The view was amazing and the proximity to good food, entertainment, and transportation was perfect for us.
I would definitely recommend staying at Sam's place if you are a low-maintenance traveler and prefer a quieter AirBnB.
