Oskar's apartment is lots of fun - great artwork, interesting books, light-filled well-designed space. The bed was probably the highlight - each side is adjustable with mood lighting and a skylight.
Location is great, on a quiet street but close to trams and everything.
We were hoping to utilise the fireplace but it was unseasonably warm so the air-con was a definite benefit. Would love to stay again, was our first time in Rotterdam (Oskar's local tips were helpful and he greeted us for check in/out and carried our luggage up the stairs!).
