Salvador is Looking for a Flat to Rent

I'm trying to keep my bills low so I'm looking for a place to crash at or somewhere affordable. I'm currently sleeping at my bros place in his walk in closet. Sounds weird but it's pretty comfy 😂 I'm paying electric and Wi-Fi here in exchange. We're all moving to a house but I don't want to take over the extra room because that will just bump my monthly bills up to an extra 600+ from what I'm already paying. If I wanted privacy I would've just gotten an apartment. My budget is around 500 a month that I'm willing to spend on rent/utilities/etc. I already have a car and phone I'm paying for so doesn't make sense for me to splurge on a room right now. Looking for a place for my old Chihuahua and I to just sleep at, no room or anything needed. I do Lyft, Uber, DoorDash as my job so I drive a lot.
