Never met Petra, just her brother Dirk, who was nice to us.
Our biggest concern is, that the apartment was not cleaned though we had to pay a „Corona-Fee“ for sanitizing.
Also the staircase to the apartment was really tiny (probably normal in amsterdam, but mentioning would be great especially for elderly).
Though these concernes Dirk showed ambitions to help us finding our way in this big city. Also we could decide on the check in/check out time what really was great.
All in all the time in amsterdam was totally awesome, but I would love to have a place where I can sleep without disgust because of the residues of previous travelers during COVID times.
