Great stay
We recently stayed at the Argonaut and loved the hotel. Everyone was extremely friendly and helpful and, while we weren't able to take our four-legged family member, we certainly enjoyed getting to meet all of the other well-behaved four-legged guests. The little chalk board near the entrance with their names on it was a cute touch, too. But, back to human matters. Since no one, or no place, is perfect, there are 2 minor criticisms. First, I'm not sure if we were in a handicapped room (there were grab rails all along the walls near the toilet), but there was no counter space in the bathroom. We had a pedestal type sink with a very small table next to it that held the soap, glasses, etc. leaving no room for personal stuff. The second complaint was that the air conditioner really didn't work very well. We were able to open our window to the cold SF air, but it was very noisy outside making it difficult to sleep, and there wasn't much of a breeze coming in because of the direction we faced. Minor issues that did not ruin our stay at the hotel.
While I would definitely recommend the hotel to others (we did and, in fact, one of our friends stayed there the week after we did based on my TripAdvisor research), we won't be staying in the area again - a bit too crowded and touristy. We saw several other Kimpton hotels in SF though that we would love to stay at next time.
