We stayed at the Mercure for 3 nights, and we will not reiterate.
We booked a privilege room with terrasse.

Cons.
- There was no desk in the room, hence, extremely unpractical to work.
- The internet connection is so slow, you cannot attend a simple online meeting.
- The shower was a complete mess: on the second day the shower hose broke and sprayed all over the bathroom. Third day, the rainfall shower had so much flow (even on minimum) that it flooded the bathroom.
- The terrasse had an alrightish view with the top of the mountains, however, it was direct on the passing road (quite noisy during the day)
- There is a railway track nearby, and the noise is loud enough even with the window closed.
- The staff is kind but not trained, 4 people were needed to find an answer to our question regarding their own services.
- If you're an Accor member (even Diamond), you do not get any benefit out of your stay: no priority check-in lane, only one welcome drink for the Accor member, no breakfast, no enhanced internet. Still wondering why they pay the Mercure franchise...

Pros
- Location near the Revard and Chambéry
- Access to the spa facilities (did not use though)

Several things let this hotel down and spoilt our stay.
On arrival we were charged a caution against our card which was 150% of the cost of the whole stay.
We were given a voucher for a free drink, yes one free drink, what do you do sit and watch your partner drink their free drink, come on Mercure if you are going to give out free drinks make it for each adult guest in a room.
The waiting staff, well the dress code was not what you would expect from a 4* hotel, jeans , white shirt and trainers! Come on we are not snobs but it would be nice to be able to tell the difference between the staff and a guest.
The barman first night split both drinks when placing them on the table, we had to ask for a serviette to dry the table and glasses.
The restaurant food and wine very over priced a bottle of Sauvignon 36 euros as it was poured it was split (same barman) the barman then noticed a piece of cork in the glass which was poured for tasting so he took the glass away, the glass was about 1/4 full, a new clean empty glass was then brought to the table and the wine poured, Come on mercure standard practice is “sorry sir, removal of glass and bottle and new bottle and glass brought to table”
The rooms were fine laid out well the shower was a very good size, there was a problem with our bed , it appears that the beds raise to waist height for the maids to make them, ours wouldn’t go down one of the days we were there, we returned to the maid trying to get the bed to go down and lock into place, we tried to help her but the maintenance man had to be sent for so we went down to the bar to have a drink and keep out of the way for a bit , on out return the maid was still in the hallway and she apologised for the problem and said the bed was fixed, which it was.
If we were to praise the hotel for anything it would be the maid, she was excellent our room was always spotless , she was always polite and the apology from her for the bed was more than what we got from the reception staff who must have been aware of the issue.
There was another problem with our room which maybe would not affect everyone but the conduit for the air conditioner in the downstairs bar area went through the room near the bed and one of our party had to buy earplugs because of the noise.
In all this hotel was a disappointment to us and has put us off booking another mercure hotel.

I had a one night stay and had a very spacious room with a balcony, which was comfortable and well equipped. The restaurant was excellent, extremely good value for the high quality of the food. Buffet breakfast also was very good. Staff were friendly. Spacious grounds in a good location and it all added up to an enjoyable visit. The guest wifi needs improving.
