This Mercure is in need of a complete refit, rooms are extremely small & little space for your luggage. Hotel is well located but there is no onsite parking & you will need to use private parking at a fee.
If it was not for the fiendliness of the staff I would not recommend that you stay here.

Very conveniently located in city centre, just 3 minutes walk from the Annecy lake and the all the atttraction are just close by. Good room. Organic break-fast. Friendly staff. Parking free in the night.

We stayed here for three nights. Bathroom very small for a big person. Although the breakfast room was not impressive to look at the breakfasts were good. No proper bar or lounge to relax. the location was good for the old town. The staff were courteous and very helfpul when making our booking for Reims. However, compared with Mercure Cathedral Hotel Reims where we stayed the next night Annecy did not compare as a three star hotel.

The hotel is ideally located between the train station and the old town (2 minutes away). Generally speaking, the rooms are attractive with good bedding. Unfortunately, we faced 2 problems while we stayed at this hotel last week: (1) The temperature was abnormally high for early October and the air conditioning system proved to be not adequate; (2) Our room was next to the elevator. As a result, the hotel room was noisy. Since the hotel was full, it was impossible to move us to another room.

I have stayed at various Mercure hotels over the year and the rating is typically is very good. Unfortunately, the Mercure hotel in Annecy is below the standard this chain is capable to provide.
