The apartement was really nice, clean and close to the city center (15 minutes by bus to the central station or 20 minutes walking to the Jordan district). Roos made us feel comfortable with already set up beds for 5 people and some advice where to go and how to get there. Even if she couldn't be there to give us the keys a friend of hers helped us finding the adress and weclomed us.
We did find some really nice places around the corner to have breakfast. The two days in Amsterdam were perfect while we felt very welcomed and comfortable at Roos place. Thank you very much!
