The Burrhus is right on the town square. Parking is several blocks away in the town parking lots. Very reasonable prices, good breakfast, the Wi-Fi worked in the common areas but was marginal up in our room. The staff was very friendly and helpful, and were fluent in English (my French language skills are almost non-existent)
We enjoyed breakfast on the terrace overlooking the town square. Numerous restaurants and shops are within a few hundred meters walk. Vaison-la-Romaine is a comfortable location for touring this part of Provence.
It is a 2-star property, nothing fancy. Note that there are several stairs to reach the rooms, no lift available so this is not the place if you have mobility issues or if you have a lot of luggage.
Our only real complaint is that the rooms are quite dark, the bedside lamps are so dim as to be almost useless. We had our camping headlamps with us, which we needed in order to read in bed.
We liked the Burrhus well enough that we extended our stay for a couple more days, we would stay here again.
