Decent place in a really perfect location. Bit north of the city centre in a new-build area, so you get quieter nights while also being really near lots of fab food places. And also right next to the (free!) ferry to the north side for plenty of trendy waterside bars and cycling out of town. And it's still only a 15-minute bus/tram/bike ride or a half hour walk to the centre to do all the touristy stuff.
The flat is neat and new, albeit slightly spartan (for example, a bare wall on one side). Bedroom spacious and cool, with plenty of cupboards. Big bonus for tall travellers: the bed is massive and extremely comfortable. Ignore the bit saying it's a double - it's bigger than a (UK) king. Felt like around 200cm long and 170 wide, at an estimate. Is that super king? It was great, anyway. I want one.
In terms of kitchen/living-area, it's all pleasant and good. Not the most thorough kitchen facilities, so I wouldn't go for this if you want to cook yourself, but that's not the point, is it? It's more than enough for sorting out breakfasts and snacks if you're planning on spending your days out in Amsterdam.
We had some tiny flaws with cleaning, but the management company sorted those out swiftly and with zero hassle.
So overall, pretty ace, and it was a great pad for a long weekend in Amsterdam.
