His house is close to the canal . The best thing is near by Amsterdam centraal
Station 7-8 mins walk.
The guest room is on 2nd floor. It is very big enough for 4 persons and very cozy design.
But the toilet and bathroom are separated from the bedroom. It is on 1st floor. You may be not comfortable to go down to take shower or do something every time . But , It does not matter . I try to think positively it is design :)
