We stayed a bit less than a week and had a great time! The place is exactly as described and the hosts provide detailed instructions for everything imaginable ranging from check-in procedure all the way to how various light switches control things.
My wife and I value privacy, a comfortable bed, serenity, and enough space to spread out a bit. The King Sized bed in the master bedroom is excellent and we had no trouble sleeping. The neighborhood is quiet and safe and we even had private parking behind a remote-controlled gate!
Florence and Alain's property has a few different units that share a common back yard but to call it a "yard" doesn't seem right. It's heavily landscaped with patios, tons of interesting fruit trees, beehives, a giant bird cage like you'd see at the Zoo, a big fire pit, etc. Very beautiful and tranquil.
The oven is a high-end Wolf unit, very cool, though we did most of our eating at local restaurants. The location is excellent because you're close to everything Pasadena has to offer as well as an easy drive to LA.
