We stayed 3 nights in this hotel for our Amsterdam city break.
Location is great - the hotel is very close to Centraal Station. Directly to the south of the hotel is a beautiful non-touristy neighbourhood, Jordaan, which is full of small independent restaurants and canal-side bars.
Rooms are well designed with nice trendy furniture. The bed is very comfortable with good quality bed linen. The room is spacious, but almost too spacious - the bathroom side of the room feels bare and will benefit from an extra armchair and some artwork on the wall. We paid an extra 10 EUR per night for a last-minute upgrade to a high-level room, which is worth the money as the views of the city from the room are lovely. Toiletries and other in-room amenities are sufficient for a 4-star hotel, but nothing special really!
Service is okay. The staff we dealt with at check-in was friendly and professional but our experience with other staff in the following days was fairly average - not rude, but also not particularly helpful!
All in all, the hotel is a good solid choice for a few nights' stay in Amsterdam. The price is very good compared to other hotels in the city. It would have been a perfect experience if the service was improved.
