The place is nice overall, very clean and well equipped. I guess it is somewhat unfair but it is easier to notice the negatives than the positives, so read that while remembering the overall experience was good.
The house isn't very easy to reach, you have to climb a serious stairway, which you can only reach through a narrow road from either side. Then there's more stairs inside to the main floor, and more for the roof. Not ideal when you have luggage. There is no real view of the canals, only a glimpse from one particular spot in the end of the second stairway inside the apartment. There is a hot tub on the roof but you are warned not to be there, even quietly, after 10 PM so we did not get to use it. They have a parking garage but the door is very low and our car didn't fit in. Not easy to find parking on the street. There is a lot of art inside which I guess would appeal to certain type of people, however for us with little children some of it was disturbing - scary or sexual. There were some maintenance issues such as light bulbs not working or a sink not working, though I admit I did not talk to them about fixing it since we were only there for two nights.
