We had an amazing stay in the Violetta appartement. The bedrooms are very big and there are so many closets and mirrors. Very convenient for six ladies attending a fashion event ;).
It's within walking distance of the main train station so very easy to get to.
Check In is at a external office (also within walking distance of the train main station and the appartment) and was super easy. They provided us with instructions for everything and quickly answered all our questions.
So I highly recommend this place.
