I stayed at Tjakko's place for about six days in early January. He was very accommodating the entire time, especially when my flight to Amsterdam was canceled so I was forced to take a later flight that had me arrive to the apartment at almost 2am. There was coffee (even a bottle of champs!) and the mini fridge was stocked with water and beer so I felt very welcome when I arrived. The location of this apartment is fantastic. Right outside the front door there are shops, eateries, a grocery/market all within walking distance. There is a restaurant next door on one side and a bike shop on the other. You couldn't ask for much more.
Keep in mind that there is no kitchen so staying here will be more like a hotel as you will need to eat out much of the time – I was definitely ready to have a kitchen again after six days! All-in-all, I would highly recommend booking Tjakko's place. He was a wonderful host and I loved being right in the hub of the city during my stay.
