Les Tresoms Lake and Spa Resort in Annecy

If you are English you are treated like a second class citizen - only the French get premium treatment. We were treated with contempt and rudeness

We did not find the property to match the descriptions on our booking site or the hotel website. It was not private or secure. The bathroom doors are clear glass with a mirror across from it, not allowing privacy in the restrooms. (Two friends traveling) The exterior of the hotel door contains a light signaling to others when you were or weren’t in your room. We asked hotel staff about the two items and they suggested we move rooms and then decided not to move us. The booking site will not refund us because the hotel said they resolved the issue with the guests. We left after a few hours due to the discomfort and vulnerability of privacy and security. The hotel did not provide solutions. The advertisement on their webpages and their actual policies including the spa, breakfast, property etc are misleading and considered false advertisement. We felt mistreated and discriminated against from the moment we arrived.

I was very disappointed by my stay in this hotel. I had high expectations and was really looking forward to my stay to rest and decompress. While the first day and night went fairly smoothly, despite having to wait more than 45min to check in (normal check in time) and the very poor quality of the WiFi (impossible to maintain connection in the room, thankfully I had unlimited data), the second night turned into a nightmare.
It appears that there was the "Bal des pompiers" in town, which is a big party in Annecy. Despite the slightly remote location of the hotel, the valley makes the sound travel far, which translated into hearing the music and comments of the DJ very clearly in my room, with windows close, and this until 3am. After complaining at the desk the day after, I was told that this was indeed unfortunate but it happened regularly when there was parties in town, and that we could discuss the matter further upon checkout. While some of the staff seemed genuinely sorry and wanted to help, the person in charge refused to make any decent gesture. They only accepted to waive 1 night of parking (9 EUR). Considering they advertise the hotel as "sheltered from the hustle and bustle of the city. Your haven of peace..." but that I still lost one night of sleep due to a party in town, I find it outrageous that this is the only gesture they deemed necessary. Furthermore, it seems that they are aware of the problem, and yet, as a 4 stars hotel, still gaslight clients and don't invest in proper windows.
So my advice to you, check the calendar of festivities in town before booking your "unique experience, in the heart of nature, combining charm, luxury and environmental commitment", because you might find yourself in the middle of a town party instead.

Have just returned from a 6 day stay at this hotel. It has some really good aspects, but also some really bad issues that could quite easily be resolved by the hotel.
The good:
Grounds - Set in a lovely spot with picturesque views of the lake.
Pool - Superb. Nice temperature, great views.
Cleanliness - The hotel is really clean.
I think that's about it unfortunately.
The Bad.
Rooms – The rooms are made up nice but this is all lost as there is absolutely no space to hang/store clothes! Worst hotel we have ever stayed in for this. There was only a 15cm rail for both of us to hang our clothes for a 6 day stay. No shelves for socks etc, we had to live out of our suitcases for our whole stay.
Prices – As an example, $16 euros for a beer. Come on, that's just taking the proverbial.
Service - So the staff were nice, but they were ineffective. I lost count the amount of times I had to wait 10 minutes at the bar, as staff were say hovering, they would finish hovering before they would then come over and serve me. Really bad.
Michelin stared. Due to the above, we decided against eating at the Michelin stared restaurant. I am sure the service for this would have been much better, but it would have made us even angrier for it to then return to normal the next day when we was at the pool !
Food - Menu was mwah. No snack bits you could have at/beside the pool
Paid Parking – Come on, they have an ANPR machine at parking gates that charges you 50 cents an hour – really? It just reeks bad taste. Charge me for the week or whatever, not for the hour. Feels like I was in a London car park.
We can’t recommend this hotel. If you have booked, don’t sweat it, just plan to eat out somewhere every night and you’ll be fine.
