I went to Rotterdam for one night with my best friend Laura and we both had a blast staying on Petra's barge. We only saw her the next morning when she gave us our delicious breakfast, but sent us all the necessary information beforehand. So the check in went easy.
The barge itself is an amazing place to sleep in. The surroundings are really quiet though its located near the centre. And it even housed a lovely little black cat that curiously welcomed us.
Overall, Petra's barge is the ideal place if you want to visit Rotterdam. It has everything you need in walking distance and shows how cool living on a boat actually is. I would definitely recommend this place.
