Other information
Number of seats: I would say about 100, on 2 different floors. The 1st floor is a mezzanine of the terminal, not so big and rapidly filled. The 2nd floor is bigger but windowless.
Level of noise: medium. Perfect in the quiet room.
Design: modern but could be better in my opinion. Most of the seating upstairs is not very comfortable for resting as you can see on the pictures. Much better in the quiet room.
View: from 1st floor only (but as I was there at night, I can't really tell what kind of view you have). No outside view from 2nd floor.
Multi floors: Yes (2)
Terrace: No
Smoking area: unknown (I didn't pay attention)
Direct boarding: No.
