Any cozy coffeehouses?

Hey all! I am looking for coffeehouse recommendations here in Downtown Houston, Heights area. I will usually go to a coffee spot every Sunday to get some reading, etc. done. I have recently been going to places like Siphon and Campesino Coffeehouse. I like them a lot, but it can get kind of crowded.

Does anyone know of good cozy, quiet (or at least to the point that I'm able to read) coffee spots here in town? Thanks in advance!
