Don't expect a lot of communication prior to your stay. This apartment is one of several properties part of a larger rental business. But after several texts from the airport and once we were into the city, Hans finally answered and had a woman let us in. She was very nice and made sure we were settled.
Apartment was extremely clean and beds were comfortable, as long as you don't mind two single beds being pushed together as one. Well-equipped kitchenette with mini fridge, very effective heaters in both rooms. Wi-fi also worked very well from both rooms.
The one thing that was very bothersome was that the door handle on the front door would fall of (literally all the way off) when we closed the door. It made us feel a bit unsafe leaving all our belongings inside when somebody VERY easily could break in. It would have been nice to have two sets of keys, too, so guests could have split up and returned home at different times.
The surrounding neighborhood was so quaint and we felt very safe walking around at night. It's two blocks from the second inner canal and a few more to the city center. Perfect location for travelers wanting a quiet environment, but very close to all the museums and canal/city center activities. Highly recommended as long as the door and lock get fixed!
