I have stayed in many Air B and B’s and Eve’s offer is up there with the best. You could spend a morning hiking ( straight from the door onto excellent trails) , back for lunch on the patio then enjoy a cultured afternoon at the Norton Simon or Huntingdon before having a delicious meal at the Italian in Old Pasadena before a cinema night out ( or in, with Eve’s Netflix). I did all those things albeit spread over two days!
Really charming accommodation with everything anyone could want.
I was a tad concerned by reviews talking about being a bit off the beaten track and ended up hiring a car as I needed one anyway for Thanksgiving weekend getaway, but rest assured Uber is a click away and in Pasadena itself the buses are excellent
