We spent 4 nights at Andrea's and Marc's home and they have been very kind hosts and we enjoyed the stay a lot. The place is located only 15-20 minutes from the city centrum and public transport (metro, tram) is very near. Everytime we can ask them for information, to change the breakfast time or check in/out time relating to our personally programm. The room was clean and comfortable and we had enough space around us, the terasse for free usage was available also (but during our stay was rainy weather). The bathroom sharing was not problem.
I can recommend this family to everybody who wants to stay in Amsterdam.
