For someone who’s been studying for 7 years now for long hours I can tell you I tried almost every studying spot in Amman from coffee houses to study lounges and nothing beats @Shoman Library it’s very quiet, but I’d say go earlier in the day (not after 10) to be able to get a comfy spot
@Watar Ziryab Resturant if you're looking for an oriental vibe and @Mijana Cafe but you'll pay more cover charge their if you're to be seated in the singer's area upstairs
