Had a lovely stay at this AirBnB for a work trip in Pasadena. The host was very accommodating for a late check-in and quick to answer messages on AirBnB website. Guest house was very clean and had everything I needed (comfy bed, fridge, bathroom, living area). There was a large backyard area that I definitely did not take enough advantage of but is nice to know. I would stay here again and recommend it to others.
A couple of things to note: the guest house is in back of the house (not visible from the street) so it was a bit hard to find the first time (late at night), it gets very hot in the house during mid-day (A/C controlled by host), and there is a heavy gate you have to open/close to park on-site.
