I've stayed there and liked it, though I agree w/ Cyberdad that the views leave a bit to be desired.
We, like most tourists, spent almost all of our time visiting vineyards, so we just needed a place to sleep.
The rooms were average; the thing we liked the most was the Lounge was open 7 days a week. There is also a nice courtyard right outside the Lounge, so you can enjoy breakfast in the open air.
They also have wine tastings every night in the lobby. We did spend some time at the pool, as well.
Good luck to you!
