We (2 adults, 2 teenagers) spent an amazing week in July at Cascina del Noce Asti appartment and we had a great time. The appartment is spotless - very well equipped and maintained, we loved it and really didn't miss anything.
Eleanor and Glyn, the owners, are extremely helpful and provide a folder where EVERYTHING you could think of (restaurant recommendations, sightseeing tips, practical information etc.) is listed in a very smart and easy-to-find-what-you-look-for way.
Cascina del Noce is beautifully placed midst among vineyards and the perfect place to relax and to visit the area of Piedmont. We will definitely recommend the place (we already did :-)) and would love to come back ourselves - next time maybe in the truffles season...
