Had a very good experience with the 080 Transit Hotel during a T2 arrival and T1 departure. Took the shuttle to T1 but was unable to enter with the confirmation alone due to timing. Made a quick WhatsApp call to hotel staff and was escorted into the terminal (bags go through security) and up to the hotel.
The room is basic but has everything you need for a transit. I booked for 6 hours and had time for a nap and a shower.
