All the personnel is dedicated to make of your stay the best experience ever. A long list of amazing services: the front desk with the concierge service being a must, parking your car, ready to help for any matter (had even suggested to go and get jewelry for my wife for Valentine's day); the terrific ski specialist directly located in the hotel giving more time than you would expect anywhere else, commuting between the hotel and the shop to get you the exact equipment, preparing all ski equipment before you get there; the personnel at the bar and restaurant deliberately ignoring pre-defined open hours to let you enjoy your experience (the menu is amazingly surprising with a mix of culture in each dish, making dinner tasteful and delicious); the masseuse at the Spa is excellent and does know how to make you feel relaxed and forget about everything; the personnel making the rooms also being very considerate, folding your pjs and placing kids safety blankets properly under the pilow...
The location is also excellent, directly on the slopes on one side, and few minutes walk from the shoping center Le Forum and all other restaurants.
Only area to enhance would be to better equip the gym room... Not that much to do there if you'd like to tone up after a full day of ski.

We spent a week skiing over the vacances scolaires in February 2011. The Hotel de Trois Vallees was a great find. We stayed in the 2 bedroom penthouse apartment. Here are the pros and cons of the hotel and the big suite:

Pros:
The location cannot be beaten in Courchevel 1850. You are both in the village and directly on the slopes.

The hotel is a really nice size - big enough to feel like a proper hotel with services, but small enough to feel intimate.

The staff of the hotel are friendly and helpful and will speak to you in the language you choose to speak. Some places in Courchevel the staff who are often Eastern European prefer to speak English to you rather than French if they think you will understand English.

The top floor apartment is very cozy and warm and charmingly decorated.

The hotel is nicely decorated in a sort of modern alpine look (although it would be nice if they got rid of the metal deer in the entry).

The onsite ski room is FANTASTIC. If you rent your equipment from that retailer, the guy who runs the shop actually sets your skis and poles outside for you every time when you are inside putting on your boots and helmet.

Cons:
The housekeeping staff is not especially thorough - there were clothes left by a previous occupant in the drawers, sometimes the turndown service would turn down only 1 of the 2 bedrooms, the number of towels and washcloths day to day seemed to vary randomly, etc.

The top floor apartment is literally in the eaves, so much of the square footage is unusable except as storage, and count on hitting your head at least once in a week.

The lift is inadequate for the number of people in the hotel and does not go all the way up to the 6th floor apartment so you have to climb a little narrow stair to get up there.

The bed is really 2 twin beds shoved together - and they won't stay together! There is a chasm in the middle, which also pulls the sheets off at the corners, so when you wake up, you find a decent part of the bed is just bare mattress.

While the rooms are reasonably priced (for Courchevel), the apartment was really expensive - if it didn't have the various issues - sloping ceilings, iffy housekeeping, no refill of the fireplace logs when requested, lift that went all the way up, etc. I might have thought the price commensurate, but as it was, I thought it was over-priced.

So, we thought this was a great choice for 1850 which itself is the best of the 3 vallees resorts, and we would stay there again definitely.

I stayed at the Hotel des trois Vallees for 5 nights with my fiancee, the experience was very enjoyable. The staff was very friendly from the moment of Check in and all through our stay.
The hotel is small and very cozy, my room overlooked the ski pistes, it was really beautiful. The ski in ski out was perfect.
All in all this was my first trip to courchevel, and it will definitely not be my last, and i would definitely stay at this hotel again

Fantstic gem of a hotel that we would stay at again. The guy running the skishop is amazingly service minded, getting hold of the exact right skiies for everyone from different shops and making sure all ski equipment is in order. The ease of getting boots and skis fiited in the shop at the hotel beats the hazzle normally encountered at the traditional skishops. The hotel is very cosy, very trendy and the staff is truly amazing. They go out of their way to organize speciel diet for a sick child, getting hold of the local English speaking doctor, leaves a deliciuos package of chocolates as excuse for a defect DVD player, and is just very presonal and attentive. The location of the hotel is ski-in/ski-out and equally easy for accessing the village of Courchevel, which can be difficult to find there.Lastly the price compared to the size of rooms and quality of food and service makes it a really good deal.
