The hotel in the heart of Maastricht - in my opinion the most beautiful city of the Netherlands - has been described as architectural gem and is indeed an interesting combination of medieval architecture and individual modern design.
As we booked several months ahead we were lucky enough to get a suite (No. 10) for a more or less affordable price. Our room was an exceptional experience as we never before entered a hotel room through the bathroom! It was a pleasure to discover how the designer respected on the one hand the historical structure and on the other hand integrated all the modern touches you would expect in a 5-star-hotel.
Nevertheless you should find the time to leave the room - at least to have breakfast in the Entresol - and have a closer look at the twist of modern and medieval in the whole hotel.
The slight flaw with the hotel is that the price is at the upper end of what we usually would spend for a special weekend. For dinner we left the hotel and went to the Petit Bonheur which is definitely a good choice for a romantic evening and had more reasonable prices than the restaurant in the hotel.
