Our entire group of 10 had a lovely stay at the Meritage: Nicely appointed & decorated rooms, GREAT Value in Napa, sophisticated but relaxed ambiance, fabulous spa, great Sunday Brunch, good service - mostly. Would definitely stay here again.
Concierge was a bit snooty and do not use the hotel shuttle if you have anywhere to be at a particular time or have a large party; it was running late when we needed it and is first come first serve, so if more than 10 people are waiting, they expect you to duke it out amongst yourselves.
Pros: price, ambiance, rooms, amenities, spa
Cons: a little out of the way, concierge a little snooty
