Booked the flat as it's close to the conference venue we were visiting with my colleagues. My flight got delayed by 4,5 hours and I arrived around 4AM, but it was no problem, someone was already waiting for me there, I really appreciated it. The flat nicely fit the 4 of us.
Only downside (for working purposes) was the very slow wifi, and the automatic perfume sprayer going off every 10 minutes which might cause problems for someone sensitive to it.
