My wife, infant daughter, and I stayed for 5 nights with at Barry and Van Matrtin’s place and would recommend to others.
In terms of location it is ideally situated with a lot of things walkable in 20 mins or less such as Huntington Gardens, Cal Tech, or downtown Pasadena itself.
The house itself is thought fully designed with a nice private backyard as well as a front patio to enjoy time in.
The hosts are also amazing as well - we in particular found the day 1 snacks and wine provided quite useful as we arrived late and didn’t have to worry about going to do groceries immediately after arrival.
