The start of our staying at this place was not great as the monoxide carbon detector was beeping when we entered the flat. The Chrysanne's Support Team's response was immediate but the maintenance team never came.
Also, the keys to enter the apartment are to be collected from a wall-mounted lockbox but there are 6-7 mounted outside the building (very low on the wall) and it took us a while to find ours.
Moreover, we had asked to have the sofa-bed opened but it was not. It was also not comfortable to sleep on.
That being said, it's a really nice place, cozy and well equipped, and the location was absolutely great, with everything within walking distance.
If you don't need to use the sofa-bed we definitely recommend this.
