I've been to 73 countries, this is hands down the worst airport I've ever been to. No free WiFi, no AC at departure gates (upper) floor. Ground floor has a bunch of expensive cafes (e.g. 10 USD for quesadilla, 3 USD for a bag of chips) and some offer Wi-Fi and good AC. Instead of overpaying for food and WiFi, I exchanged my remaining cordobas back to USD even at an unfavorable rate. There are fruit flies everywhere.
On both floors there are a bunch of overpriced souvenir shops that sell the same items. The only normal place is Subway sandwich. Upper gate floor has a VIP lounge, 2 cafes and 3 restaurants. There is no display of flight and gates info, I don't even know what my gate number is (but there are only 6 gates). Announcements are only in Spanish!
Only good thing was going through security and customs was a breeze. I didn't even fill in and submit the exit form. You can keep your water too.
Safety is not an issue, people are ok here. If you don't rent a car, Nicaragua does not have Uber, you need to use Aventon or inDrive app, or get ripped from taxis here that don't use meters. Good luck navigating this dump. I'm getting heatstroke here everyday and I'm outta here!
