Location: right near a tram stop for the number 4 line - which goes right to Central station, passing useful stops along the way. Also very close to Amsterdam RAI station (5 minute walk) which can be used to go to the airport. We were also able to catch a bus straight to the airport, the stop not too far from the house. (5 minute walk). Very nice and quiet neighbourhood.
Hosts: The best. Janet and Guus are the nicest. Were able to help us with any questions we had. Janet went through great lengths to help us find the right bus stations and times. We were also provided with the local transport cards, which were already topped up with money. All you need to do is pay the different at the end of your stay!
House: We had two large suitcases with us, so walking up 3 staircases was a bit tough - but we knew about that before hand anyway and managed. So just keep that in mind - although most places will be the same I assume, from looking at most buildings. The house itself was very clean. A small fridge, coffee and tea is provided, as well as clean towels daily. Shower gel and a couple other toiletries also provided. Pretty much what you see in the pictures is what you get!
Overall: 5 stars. Can't think of anything else we would have needed.
