Pillows too thick.

We stayed in one of the apartments. Was very clean, comfortable and tastefully modern. Excellent breakfast.

Dinner our last evening was a bit bland and the bathroom in our classic room was a bit small. But clean and well equipped. The hotel offers better rooms for a small add-on.

Good location for exploring Rennes and Bretagne. Very nice hotel, cozy feel but what really stands out is the staff. I have travelled the world on business for 40 years and stayed in many luxury hotels but the Balthazar Hotel is one of the better experiences I have had. Full marks to every member of staff throughout the four nights we stayed at the hotel.

Nothing we didn’t like!

Outstanding service, comfort, quiet hotel with extras such as use of spa, minibar included and comfortable public areas for relaxation. Great location and hotel recommendations for local restaurants. Visit the nearby museum of fine arts for free.

We had a wonderful stay at this hotel! It’s perfectly located, right next to everything you might need, from restaurants to attractions. The service was excellent and the staff were incredibly kind and helpful throughout our stay. They offer a valet service, and the valet was very professional and efficient. As part of our stay, we also had access to one hour at the spa, which was a truly relaxing experience. Overall, I highly recommend this hotel, everything was top-notch!

This hotel was the best hotel for overall aspects of all the seven hotels we stayed in during our trip

Hotel itself is great. However if you have a car I would suggest perhaps Rennes is best avoided as they take the concept of hostility to car drivers to a different and somewhat ridiculous level.

A delightful place with delightful staff. We arrived with car which is, in Rennes, an inadvisable thing to do. Spent an hour driving in circles round the inpenetrable one way systems, not more than a couple of hundred yards from hotel. Eventually parked in a space and walked there, somewhat frazzled and bad tempered. They were absolutely delightful. One of them volunteered to go and get the car. Got it. Sorted it. Wow! Hotel itself is lovely. Very elegant. All the right bits in the right places. Close to centre of town. Nothing to dislike. Everything to like.

Our room was small there was only room for 1 case and we had 2. The staff forget to send up our cases so we were without them until we reminded them. Food and alcohol were very expensive

Good position

This should be private to the management. We ezperienced several bedbug bites diring our stay 😳 But given the otherwise excellent stay did not want to explicilty mention it to reception- obviously embarrassing. I had an aternoon nap because of the heat - my companion worked - so it was quite obvious the next morning when we had similar bitemarks.

Well appointed. Luxurious. A\C struggled with the heatwave - but managed
