What a well run hotel. Beautifully maintained, wonderful breakfast and a feeling you are in an Austrian ski resort.
Owner managed, he is there every day, and it runs flawlessly. We would look no further in Vail.

this was my first stay in vail , we went there for skiing. from the very first moment we felt comfortable and the whole stuff is very friendly and helpful. On arrival we got our room. As I could hear the music from the bar i aksed for a more quiet room which i was given the next day in the morning. For someone who likes to go out in the evening its not a problem as music stops at 11 pm. Coming from Europe and skiing the whole day i like to go to bed early so a quiet room for me is extremly important. The Breakfast, included in my room rate was awesome. I love american breakfast and found everything from eggs benedictine to french toast, fresh fruits, croissant and may many more. The Ski Concierge near the Gondola is a wonderful service too. I sure will come back one day.

I spent a lot of time choosing a hotel for a weekend getaway. I wanted to be in the lap of luxury but didn't want to spend over $850-$900/night. I settled on the Sonnenalp because of the reviews of the service.

The good: Indeed the service was stellar. From the moment I made the reservation, the concierge was in contact with me to ensure all of our needs were taken care of (bed choice, dinner reservations, ski rental, spa appointments, directions, etc). Every employee wanted to help you. Every question was answered politely. Every need was catered to. The maid service actually cleaned the room. Bathrooms are beautiful with GREAT towels. The breakfast buffet was delicious and the dining room was beautiful (especially with snow). Water, ice and cookies delivered everyday. I've heard wonderful things about the spa but we didn't have time to try it out.

So, why not 5 stars? Well... The rooms aren't glamourous. Honestly, it might be time for a remodeling. Or maybe it's just a matter of taste. The Sonnenalp is more of a European feel than an American Four Seasons. So think stark white, plastered walls and basic pine furniture with solid fabrics. While the rooms were large and it was awesome to have a fireplace, the decor is basic and sparse. I got really, really tired of the print carpeting all over the entire hotel. Also, they upgraded our suite which was nice, but the suite they gave us was on 2 floors. Again, a plus and a minus. Nice to have extra space but climbing downstairs in the middle of the nights after a few drinks was rough. Plus, the upstairs was so tiny, I felt like I was sleeping in my grandma's attic.

On a very personal note, I really didn't like the help's uniforms. I found the peasant style dresses embarrassing.

Last, this property is not ski-in, ski-out. You have to walk about 3 blocks to their "club" which is in the basement of a ski shop. There you store your shoes and things while you ski and at night you store your skies. The hotel is central to the restaurants and shopping, just not to skiing. Not many hotels in Vail are slopeside.

In conclusion, I probably wouldn't stay there again because I personally enjoy a more modern hotel but I would suggest it to others based on the incredible service and nice bathrooms.

Stayed at the Sonnenalp for 10 days in February 2013 (ski-ing trip with my wife). Very hard to find fault with the place - check in was swift and friendly (thanks for the room upgrade), then escorted to our room and the heating / appliances etc were explained. A nice touch was the humidifier which isn't always supplied in hotel rooms in Vail but is desperately needed. We had booked a basic room but were upgraded to a mini suite which was really lovely - comfy chairs and a fireplace. We also had a small balcony which was useful for chilling wine. There is a walk-in wardrobe; the special feature of the rooms is the bathroom - huge, underfloor heating, double vanities, separate shower and large tub.
Breakfast is taken in Ludwig's, the a la carte restaurant. There is a wide selection of hot & cold dishes with a particularly good fruit selection. But the best feature of breakfast is the service - OK it's a buffet, but the servers are all very attentive and will bring you coffee, juice etc. We never had to search for a server to bring a coffee refill - it was always done before you even thought of it.
There are 2 on site evening restaurants - Ludwigs which is a fine dining fish speciality: unfortunately we didn't eat there this time. The alternative is the Bully Ranch - pub style, very american, good solid food but beware of portion size: it would be wise to order appetisers first and then see if you have the stomach for a main course. If you want apres ski, there is a pianist in the bar in the afternoon and usually a singing act in the evening.
The Sonnenalp is a 5-10minute walk to the ski slopes. You could take the in town (free) bus to the Vail Village stop although you would still need to walk a little to the slopes from here. Most guests are happy to walk from the hotel as skis and boots are stored at the Bridge Haus just 50 metres from the snow front. The Bridge Haus is a full service ski concierge which really makes the holiday - the guys there are just fantastic. Your skis and boots appear by magic in the morning (boots are stored on driers) and they always have a friendly word. The best ski concierge we have had in 30 years of skiing.
There is a spa complex with indoor/outdoor pool, hot tubs, steam room, sauna and gym. My wife and I both had a massage - very professional, effective, relaxing; unfortunately, the price reflects that you're in a five star hotel.
Vail has many new swish five star hotels but I don't think that many could match the Sonnenalp for service, facilities and old world charm (and price). Can't wait to return.
