We stayed with the Holiday Inn for 4 days at the end of August 2017. It really is a no frills hotel. The room is quite plain, but it was clean and comfortable, and it was a great size for Europe. It did have funky blue lighting in the side of the room that made it a little dark at night even with all the lights on. The staff was very friendly and helpful. They called cabs for us and gave us information on the surrounding chateaus. It's a little far from the city center, but we knew that going in. It was about a 10 minute walk down to the Chateau Blois, and a 20 minute walk to the train station.
The breakfast at the hotel is included. While the food it nothing life changing, it is very well stocked with a large selection of breads, juices, coffee, meats, cheese, and eggs. The breakfast staff was very friendly. It was a great way to start off the day.
This hotel will not blow you away, but if you just need a clean, simple, straight forward home base with breakfast and plenty of space, its a good solid choice.
