Overall Was Great -
The airbnb is a great deal for a studio in a really nice, safe area of Altadena/Pasadena. You can start your day with a run with the most amazing views. They had a large mini-fridge, laundry, fancy air heater to deal with chilly mornings, hot plates, cutting boards, coffee machine, microwave, and 4 pillows if you are wondering about those features. We both are thinking of staying there again in future.
A Few Downsides but Would Stay Again -
If more than one person is staying there, please beware that you are paying for a studio. If one of you is an early riser, the other will be woken up when the early riser uses the bathroom or microwave or settle yourself on the lounge chair for work call. The shower has too small of a volume for a 6 foot, 2 inch guest but is reasonable for a 5 foot, 5 inch guest. The shower may be uncomfortable if you need a larger bathing area.
Tip for Checking-In -
We were confused about how to get into the airbnb in the dark. We wandered into the front home's yard looking for the back yard but eventually found it. I think it would be helpful to say "Enter on the right hand side of the property, up the drive way, through the gate. The entrance looks like it lies between two properties since the property in front of the airbnb has a fence that wraps around their yard".
