I stayed at this hotel 16 years ago and enjoyed it enough to return. It has been renovated since then, and it still sits right in the middle of the tourist spots: the basilica, beguinage, etc. Best of all, if you are interested in the Tongeren Sunday Antiques Fair, it starts right outside, in the hotel courtyard.
The staff are very helpful. For instance, I asked about the cost a taxi to Maastricht. The next morning, they had the fare, as well as the times/costs of alternatives, like train and bus.
Finally, the hotel restaurant is very popular and its menu has a wide selection of delicious items.
