We only spent a night in Marieke's place and it was super cozy and chill, with a great location. We particularly enjoyed the swing-chairs in the balcony. Also, the kitchen was neatly modern and full of useful amenities. The bedroom was spacious with a neatly integrated bathroom (shower/sink).
All in all, it was a real pleasure staying at Marieke's place and I would recommend her place to anyone coming to Rotterdam.
