Just returned from a week at the Portetta in March. We stayed in a family room with valley view on half board. In nearly all respects we loved the hotel and I think you will struggle to find a better option in 1650 if this is your budget.
Firstly the room on the first floor, was large. It had technically a valley view but most of it was over the area at the back of the hotel and the actual valley view was obscured by another building. That was a shame and those wanting a good view might want to check what else is on offer. The bed was two singles locked together and on the hard side with quite unyielding foam pillows. There was a good area with a tv and sofa which converts to a bed. The second bedroom was bunk beds and perfect for children. The bathroom was fantastic. Large with a big bath with marble surround and a seperate large shower. Very good water pressure so you can run everything at the same time with no problem. The loo was not in the bathroom. There was a good run of cupboards in the entrance with enough for a small family to hang clothes, ski wear etc. The room was kept beautifully clean and tidy twice a day and all the copious towels were changed in the bathroom.
We stayed half board and have absolutely no complaints on this front. Breakfast was endless with very few boxes un-ticked. A huge choice of cereals bread yoghurts etc etc and a menu if you wanted something hot. My only complaint was that the fruit juices were not fresh in the true sense. In the evening there was a four course dinner which, though not truly gourmet, was very good indeed considering the large number of covers they were serving. The fish buffet evening was a highlight.
Regarding the skiing - the ski room was the best I have ever experienced. Wonderful sofas to sit on while the brought your warm boots and a very relaxed service from Gilbert Sports who run the concession if you need to hire things. It is also a small shop if you need a pair of gloves or anything else. The hotel is not ski in ski out and you have a short walk to the bubble to get up to the top first thing in the morning. Coming back you ski right up to the hotel.
The most outstanding feature of the Portetta though was the staff who were, from my experience, consistently charming and helpful. We had no cause to complain about any aspect of the service throughout our stay.
So in my opinion and with very few reservations, this is a great place to stay in 1650 if you can get a room. I heard a departing guest trying to book a loft for the next couple of years of Christmas holidays with no luck! We hope to go back some day.
