check in was super easy and smooth using keypad entry codes. the parking lot was gated and felt safe and we had space to park all three nights we stayed, although on a weekend it might get crowded so coming in at a later time (like after 10pm) may mean you won't have a spot. the presentation of the room was very clean and simple and the aesthetic was pleasing and well done -- clean white walls with small touches of houseplants and wall art, clothing rack etc. WiFi was decent but dropped on occasions -- for those working depending on the room there may not be a full sized desk or table. however there's a spacious common room that is available with tables and chairs.
the location itself was prime -- close to downtown LA and koreatown, which is where we primarily frequented. the surrounding neighborhood is mostly working class, nobody bothered us and we felt as safe as you could in a downtown area. on certain nights there might be taco stands and various food stalls around the streets so it can get crowded and lively.
as mentioned in the listing page there's potential encounters with some homeless and their tents and belonging, etc. they give you your space and don't bother you. appreciate the honesty from the host and the heads up -- many parts of LA face similar conditions, it's just what it is.
the alleyway is narrow and on some blind corners a car might be coming from the other direction -- drive carefully and be aware.
I personally would feel safe walking around the area at night but I would be aware of my surroundings just as you would in any downtown city area. I'd recommend leaving through the front entrance (so not the parking lot) if you're planning on walking around and checking out the neighborhood as cars come through the back alley and it's narrow.
