We had a great stay at this hotel/apartment. There is an elevator for your luggage and also apartments on the first floor where we stayed which is rare for Amsterdam! Concierges are very helpful and it's nice to have free coffee and a vending machine available in the lobby.
The apartment itself was a good size for 4 people, the living area and kitchen were modern and stylish. The bedrooms are small but still comfortable along with the beds and covers. The shower and separate bathroom along with the hallway to them are small so be aware. Could be uncomfortable for heavy wet people. Besides that the bathroom was clean and came with toiletries. There are also very few windows that open so circulation in warmer weather could be a problem but was fine for us with the included fans.
Overall we really enjoyed our stay and would recommend this hotel like experience. It's a much nicer stay than most typical Amsterdam Airbnbs.
