Loud! Not a quiet place inside.
The walls are very thin. You can hear the people chatting in the room beside you, and the foyer area. If anyone was awake in the area, you can hear them.
If your a heavy sleeper though, the location is amazing, the staff are friendly and helpful and lots of food options around.
It should be noted that although the pictures show a basic kitchen in the rooms, it’s 25 Euro to use it!
