Petra is a very kind person. She arranged an earlier check-in for us and answered always within a few hours. The appartment is very well equipped and the terasse is definitely a highlight. It was not dirty at all but also not super super clean. And I thought the bathroom and bedroom were bigger - they were quite small. I would definitely recommend to stay at Petras place even if I think it is too pricey (but maybe that's just what you pay in Amsterdam)
