the staff, the restaurant, the rooms with LCD and DVD, the pool...actually everything
the only one we could find, it is too close to Napa...
We have stayed the first two nights in another hotel, because the River Terrace was not available, but when we finally could move in we were more than surprised. The welcome and support of the staff was very refreshing. The rooms are big with a wonderful bed. The TV was already good, but the DVD rental for free was a huge extra. Not too forget the bathroom, everything was clean. The restaurant had very friendly service and even the choice could have been maybe bigger, the quality of the food was great. The breakfast, that we had on the terrace was very good and quite various. After all, one of the best hotels we had on this trip and the only thing we could find to complain about, we could not stay longer, because we had to get back to SFO to catch our flight
