I really like staying at Rosie's place, the house it is very good located, tram is so close, no more than 5 min walking, it takes you directly to museums, center, central station, etc. coming and going to airport is also easily and very close. The Rai Exhibition Center is also very close, you dont need to take tram, just walk. The room is clean and confy, bathroom is clean. Breakfast is delicious!
Rosie and her husband very nice people, they recommend you where you can go and visit. You have your own key.
If I go back to Amsterdam definetly I will stay at Rosie's house.
