I was there with 3 other roommates for a long stay. Overall a pretty good experience. Carlos is very responsive and reasonable, and will go out of his way to help out with any issues or requests. The place itself is alright, the furniture/amenities are on the older side but are still comfortable and usable. Kitchen was well equipped with cookware and dishes, and there was some stuff left over from previous tenants that you can use. Internet was good and definitely usable for work-from-home purposes. Note that if it isn't working properly, let Carlos know since I think he pays for internet on a month-by-month basis which makes sense for an apt that isn't occupied all the time. We also had some issues with ants and the water boiler leaking, but Carlos was pretty quick to either give us stuff to deal with it (for the ants) or come over to fix it himself. Location is pretty good, area felt safe and was within walking distance to some good Mexican food. It's on the outskirts of Highland Park so it's pretty quiet at night and the busy parts of Highland Park are still within a reasonable walking distance.
TL;DR, the place is on the older side but is still livable and comfortable. We had a couple issues but Carlos will take care of you. Pretty happy with the place given what we paid.
