Carlos' apartment is a very nice, huge space in a great location. I stayed here over a long weekend with four friends and there was plenty of room for five adults--everyone had a bed or couch to themselves. The living room and kitchen were both large and were great, cozy spaces for everyone to hang out in. And Carlos' dog, Blue, was a total sweetheart--he would excitedly greet us whenever we left or returned to the apartment. If you love food, there are a variety of Latin American food vendors who set up on the sidewalk outside daily and some of Koreatown's best restaurants are just a short walk away.
Admittedly, communication with Carlos was a bit less than smooth. I get the feeling that he has been burned by some bad guests in the past, as he seemed a little suspicious of us throughout our stay. He seems to send automated reminders via AirBnb about things like turning the lights off and for whatever reason, this caused a message from him about his checkout procedure to not go through until the next day. We ended up doing the check-out procedure with him before we left but he was upset that we hadn't followed his rules. If you choose to stay here, I would recommend verbally confirming the rules with Carlos when you check-in and proactively reaching out before you check-out, just to ensure you're not missing anything.
