That's a great price to MPM. Sidebar I was there in 2018, one of the most corrupt countries I've ever been to, but really nice. You can also easily go via minibus to eSwantini for those collecting countries.
Here is my Trip Report in Maputo , eSwantini and the lounge at MPM which was used by TAP at the time. Also the menu in Business was super weird ex-MPM, pretty small dishes.
