IF you're on the A380 , you'll be in for a treat with the onboard showers and J bar
Even if you're not, EK F is very good and I am sure you'll have a great flight.
Storage space varies across the different aircraft/flights but is also generally quite good.
Post your flight numbers to get better feedback.
Have a look at a few EK Trip reports (TRs) in
Trip Reports to get an idea of what you can expect.
Cheers,
