Great appartment, really functional and nicely decorated. The location is a good balance between decent price and easy access to the town center. You also have a large selection of bars, coffees and restaurants nearby if you want to stay close after a long day. It is extremely quick and simple to get from the airport to Joost's by public transportation and Joost gave clear and detailed information to achieve this.
I did not get to meet Joost but he kept checking on us and everything went seamlessly.
The only downside is that both bedrooms are sharing a wall and you have to go through one from the other to get to the main rooms
I highly recommand the place. Good tip : there is everyday a fresh market a few streets away from Joost's place. You can buy local traditional delicacies at a good price for lunch or just to take home. You will have a lot of fun poking around, plus it is on the way to downtown.
