Mik & Isabelle welcomed us warmly. The apartment is nice and big- comfortable for 3 adults. Mik lent us 3 bikes and when one had a problem, he repaired it immediately.
If you need to park your car, here's the best way (it was a bit confusing, but we figured it out)
1) Unload your stuff at the apartment where you can park for a couple of minutes without any problems.
2)Drive to the Arena P&R parking (see website https://www.amsterdam.info/parking/park-ride/). It's a 10 minute drive. Once inside the parking garage, make sure you use the P&R ticket entry to enter the place where you can park.
3)Go to the blue machines and swipe your parking ticket and buy the number of metro tickets you need for the city center. You must get off the metro in the city center to validate your metro ticket. The first stop on line 54 which is considered to be in the city center is Amstel. This is also the closest to Mik & Isabelle's (about 1 km). You can go directly to Amsterdam Central station if you want and take the line 4 tramway back out to Mik's. Just hold on to your metro tickets and your parking ticket.
4)When you want to get your car to leave Amsterdam, you need to use your same metro ticket, enter either at Amstel or any station between Amstel and Central. Take the metro back to Arena station, use the red machines to swipe your metro ticket and parking ticket. Pick up your car. Drive back to Mik's to get your stuff.
If you arrive at the parking garage after 10am, you can stay for 96 hours, paying only 1€/day.
I hope this is clear because, frankly, it wasn't for us even after reading the website.
