(I only stayed there for about 14 hours for a long layover.) The place was close to the airport ($15 Lyft ride from the airport and a bit less for the ride to the airport) and just as described (very nice private bathroom; ok bedroom). It was easy to get in although I arrived late at night. The hosts left a bottle of water and an energy bar in the room to welcome you - overall they were very nice and welcoming.
In the end I don't think I saved all that much compared to staying at a hotel considering all the transportation costs (especially if I stayed at a hotel with free airport shuttles), but it was a good experience.
