we had overall a good stay but the check-in process was a bit tedious, especially for people not familiar with the area. we understood that the building/apartment was "party free" and had strick noise rules but the first night the neighbours had a massive party.
Also, not all the power outlets worked.
We also booked for three people and had to make up the couch/sofa-bed ourselves, not normally an issue but we didn't feel comfortable opening all the cupboards and trying to figure out where everything was. we would stay again but for those looking for a Luxe apartment, this isn't for you.
