The short version- better than a hotel, but not quite a great apartment.
Good - The apartment was in a great location. Right off the canal, which especially at Christmas, was delightful to be so close to some Christmas markets. Bus 60 is a half a block away, which takes you directly to Tivoli and the central station. The beds are comfortable and the rooms are big (for Europe). Great water pressure in shower. Convenient to have a washer. Fast internet.
The less than good - There are no supplies at all. There was no laundry or dish soap provided (we had to buy it, then took it to our next place). The kitchen is more like a kitchenette. At the very least, I would suggest adding a toaster oven, as it isn't easy to only cook via the stovetop. If you hang out during the day, the apartment will smell like fried fish (delicious, and i did eat at the restaurant downstairs, but...). The big bedroom is loud all night, even w/ a white noise machine. There is no dryer, even though it's listed.
