Good place to stay before a flight - No contact checkout allowed me to leave the building by 6:01am, walk 1 minute to the bus stop, and make it to the airport by 6:15am.
One thing i really did not like was their baggage storage. The bag storage room was bascially in a hallway that anyone in the hotel could walk through. If you are travelling with any valuable gear, and you arrive before your 3pm check-in time, I would not plan to store your bags, since they wont store it behind a locked door, or give you a tag/receipt for holding it. They had 3 office rooms on the ground floor, which seems like alot for a small hotel - I would recommend to management that they create some space for secure baggage storage in the future.
Otherwise, this is a solid spot for a breif stay in EDI, and perfect if you're about to fly.
