Robert's apartment was very dirty and messy when we arrived. After 5 hours driving, I had to clean the kitchen and the toilets - a dirty towel on the floor, the floor was fool of hairs. There were trash cans in the entrance.
You said that your appartment is able to host 6 people but actually is not. There is actually only 2 double beds, 1 mattress on the floor. A leather sofa is not a bed, I am sorry. When we arrived we were hosted by your neighbour who treathened us whereas we were really quiet as you mentionned in your message. Honneslty, I loved Amsterdam and your apartment is well situed, but when you rent an apartment the least you can do is to arrange and clean it before people arrived in it. I hope you will be more careful for your next host.
