A very practical Self Serviced Apartment by company Huswell. Clean and fully equipped, easy communication via Huswell portal (where you have to register first) with quick response during their opening times. Perfect for a business trip.
Only point to mention: be aware of some "hidden" costs, e.g. linen is not included, and it was already mentioned in the airbnb description. But - booking linen is at 45EUR for one-time delivery (why?) plus min. 10EUR/day or 20EUR/day if you want to have it prepared first day. Self check-in (keybox) after 17h is free, but one hour earlier costs 39EUR extra, etc.
