Overall, this is a very good deal! There are a number of relatively minor gripes, but on the balance this is such huge value: good parking, a very nice fridge and range, good tiles in the shower, a semiprivate porch area in a calm if not tranquil part of SoCal.
Glendale is centrally located if you want to explore the Southland broadly, since you're near Pasadena, easy access to the SGV/626 and they Valley, and of course you're right across the city line from Atwater, Los Feliz, etc. It's kind of perfect.
Minor things: the shower is dangerously, unsafely, slippery. There needs to be a good shower matt (as of 1/17/22), so check the listing to see if it's been addressed. The walls are scuffed, the floors are kind of spongy, the glassware is lackluster, the mattress isn't great, the lighting is harsh, and the walls are quite thin. But I'm nitpicking when it does the essentials very well and for an excellent price.
