I rented this place for my in-laws. The room is nice but we realized that for two people, for a month and a half, it's too small. The landlords are kind but really, a little too pushy. They texted us for anything, and you know, when people are on a vacation, they want quiet and to feel independent. In a month and a half, the owners needed to enter the apartment about 5 times. Once they asked us to let them in to install a portable A/C, because the A/C control is in their home so there wasn't a way for my in-laws to activate it when they needed, and in Pasadena/Altadena, in the summer, it gets extremely hot. Besides, according to the ad, the A/C was available in their room. Then they had to access the rented part for plumbing problems two times. Why didn't they do it before renting it? Anyway, again, Ken and Ellen were nice to my in-laws but, again, when you rent a place for a vacation, you don't want to feel somewhat uncomfortable. Just consider that the only door that separates the "unit" from the owners' has neither a lock or a key on the renters' side; only the owners can lock it or unlock it, which is to me absolutely unacceptable when it comes to privacy and peace of mind. On top of that, they could have cleaned the barbecue prior to our arrival. My mother-in-law had to do it. Having said that, Altadena is lovely, and I still think that if one wants to have a vacation in the San Gabriel Valley, is one of the best areas where to rent.
