Kate is an amazing communicator and will give you any recommendations or suggestions during your stay.
If we ever needed anything (shampoo or help with the coffee machine), she responded timely and helped out! Absolutely lovely lady! She even left us a vase of beautiful sunflowers.
The apartment is one bedroom but has all the necessities. Clean, tidy, and a close walk to lots of main attractions of Amsterdam.
The stairs are very steep and the apartment is on the very top floor (fourth if I recall correctly) so make sure you are prepared for this and physically able.
