On sundays, Vita Tower B will close its main lobby. Please try to enter the building through the back entrance and walk up the stairs to the second floor.
Please use this map to find the back entrance. You want to walk to the road behind Vita tower (where the garages are).
Here is the front entrance. If it is locked/closed, follow the red arrow to get the back entrance.
Here is a image of the back entrance. Take this door and walk up to the second door.'
