On my 4th visit to Amsterdam, I chose the Doubletree for the first time. I was presented with a warm cookie and recognised as a Gold HHonors member on check in, and upgraded to an executive room on a high floor with a balcony overlooking the city - probably the one of the best views in Amsterdam. The view from the SkyLounge is also fantastic. The balcony was of use to me as a smoker (too many hotels are now 100% non smoking, I appreciate the ones that allow it in certain rooms/balconies!). The hotel is situated right next to Centraal Station and so is in a great location.
The management were very friendly, visiting me on the first night to make sure everything was up to standard.
My room was large and clean, with a comfy queen bed and floor to ceiling windows. The iMac is a great touch as it allows you to surf the net and watch TV as well as listen to music with the speakers provided. The bathroom was also very clean, with both a shower and a bathtub. Although the minibar was empty which I found strange - you're instead advised to call room service for drinks packages.
I had use of the executive lounge which is open 24/7 (canapés and wine served 7-9pm), which is nothing special but a good facility to have. You're able to sit down with a coffee and relax, or print documents etc.
Breakfast was included with my room and consisted of an expansive buffet selection of American, Asian, British and Continental style items, all of which was delicious. I also made use of room service twice and on both occasions was served a delicious meal promptly. I called the concierge on one night to recommend a Chinese restaurant and he booked me a table at Geisha - highly recommended.
I will certainly be staying here again on my next visit, and hopefully will be allocated the same room! I'd also recommend downloading the Uber app to get around the city - €10 off your first trip using promo code: '3d733'
