Though a little hard to find, Mari Marinez was an overall nice experience. It had a nice atmosphere, calming music and the threading was done in a separate room. There wasn't a place to wait other than some empty manicure chairs, which was fine but make sure to make an appointment ahead of time. The actual threading procedure went well, the lady checked several times to make sure she was doing it how you wanted. A little bit pricey compared with what I pay in the states, but it is conveniently located for me. Will definitely go back!
