I visited Amsterdam with 3 friends.
Saskia was an awesome host. Before we arrived, she gave us some helpful tips, she even warned us about possible noise due to some construction works in her street. We made all the arrangements without any problems. Once we got there, everything was as described - place was nice and clean, really cool. Saskia left us some fruits, teas, coffee... We had everything we needed.
Apartment is a bit away from center, but we walked there every day and it was very nice. Apartment is very close, though, to Jordaan, which is very cool part of the city. All in all, apartment position is excellent - it is very quiet, but many restaurants and coffee places are close.
I would definitely recommend this apartment.
