We stayed at the Allegra Isla for our first holiday in Switzerland. We found the contact with Lisbeth & Julia to be easy as we have no German. After some considerable confusion over the terms of the internet booking we would recommend that you make sure exactly what you are paying for and that the hotel accepts your booking made via the web.
The hotel expects payment in cash and I had to ask to pay by Visa.
I have to say that the whole booking process caused us some stress as the prepayment wasn't required and I had to ask several times for clarification.
We were late arriving (due to delays at Terminal 5) and we were gratefull that we were provided with food with no fuss.
Our room was clean, warm & tidy. The balcony had a splendid view. The breakfast was continental style which featured the best musli I have ever tasted. Dinner was single choice menu with a 15CHF surcharge for the childrens menu (a bit steep for chicken nuggets and chips)
Nevertheless, the food was nice enough,although we felt relegated to the side dining room and a bit out of it.
The waitresses are friendly and enjoyed a laugh with us.
The owner, Lisbeth, visited us every meal time and generously offered as much food as we could eat. 'Just ask' she'd say. We did once and we were impressed !
The free ski bus stopped nearby and you can buy the lift passes at the hotel if required.
There is a free heated ski equipment storage room.
All in all we loved Arosa and will return one day.
To sum up, an comfortable, friendly adults hotel with insufficent facilities for the younger guest.

I stayed at the Allegra Isla from 22 to 26 Feb 2007, with my husband and two children (boys aged 9 and 7). We had booked a family room, south-facing, with balcony; we were very pleased with the accommodation as the room was comfortable and clean, and was properly prepared for us on the afternoon of our arrival. Often hotels do not arrange family rooms according to how they have been booked; numerous times we have arrived at a hotel and have to pester reception for extra beds, towels, etc.

We were made to feel extremely welcome at this hotel; we speak very limited German, but the staff (particularly Katrin on reception) went out of their way to be helpful and friendly. Katrin's English was excellent and she was most thorough in her directions and descriptions, as we needed to be pointed in the right direction for ski hire, ski school, bus transport around the resort, etc etc.

The food provided (we chose half-board) was exceptional - fresh, flavoursome - and the children's meals were way above average; they were served filled pasta, or vol-au-vent, for example; essentially the meals were imaginative and used local produce.

We liked this hotel very much indeed; it is a quiet, family establishment with charming staff and excellent food, and I recommend it highly to anyone wanting peaceful accommodation which is near to the ski bus stop (about 150m away, a free service which runs regularly throughout the resort) and which provides generous, wholesome meals.
