First of all i would say thank you Johanna and your sister for hospitality my family. We (4 people) stayed in the house for 5 days. I want to note the accuracy of advertisement. Very great location in cozy and quiet district near central of Amsterdam. Big house with back yard, bike in addition, canals, flowers, very delicious ice-cream in 3-4 minute walk. House has really all devices that you would need like wifi, washer, hair dryer, TV, etc, etc. In my opinion this offer really has everything that you need for short or long stay.
Johanna and her sister every day were wondering whether we are good staying. So easy to communicate with host.
If I happen to be in Amsterdam again, I stop here again without hesitation
Great choice!
