I had originally booked four nights here - Saturday through Tuesday - but was informed late on Thursday that due to a "technical error" they had overbooked and would put me up in their "brother hotel", the Park Hotel about a 5 minute walk away.
When I arrived on the Sunday they were very apologetic and upgraded my room to a suite, although I didn't know what to expect with what I originally booked so I can't compare if what I ended up was better than what I originally wanted.
Not to worry, as the room itself was great: my windows opened up to the canal and the bar downstairs, which attracted a very upmarket and trendy Amsterdam crowd. I headed down for a few drinks on the Sunday night and really enjoyed myself, although it was understandably very pricy.
The room had a very spacious and comfy bed (with many a pillow!), gorgeous bathroom and outstanding bathtub.
Room service was outstanding: a delicious range of burgers and steaks from The Butcher, a local burger joint voted best in Amsterdam. Truly AMAZING burgers. Pricy but well worth it if you want to order in, which I did three times while working from my room.
Service overall was quite superb and very generously informative on everything Amsterdam.
My only major gripe is the location: while it's close to the trendy De Pijp area, Albert Cuypstraat is a very ugly street -- not a tree in sight -- while the walk to the city center is about 2.5km, so a tram ride is a formality.
Also, while not an issue for me, the De Pijp red light district literally starts right next to the hotel, step out and walk along the hotel and you'll be greeted by working ladies. It's not an issue really as the area is safe and generally very quiet, but this may be confronting for families, although I assume they aren't the core demographic the hotel is trying to appeal to (the young, professional and wealthy appear to flock to this hotel).
