Yesterday while walking down the street in the centre of Rotterdam, I came across a shop which totally fits my taste - Flow Wonen. They have a good collection of furniture, paint, candles, accessories and art.
I loved to see all the brands I like so much like Dutz, It's about Romi (including their City Lite collection) and many others. You also can ask for interior advise there.
Today I am going back there and study the shop better :)
