This hotel is beautiful. I love this hotel and I say that despite the fact that I hate Union Square. Abri is super smart in terms of technology--HDMI, etc to hook up your iPad, etc to their tv--AND they provide wine glasses!!!! Staff were so friendly and helpful. It is very conveniently located. We may be making an overnight at Abri as part of our annual anniversary celebration.
The lobby was clean & nicely decorated. The staff at the desk took care of us right away. Our gear was stored tho it was hours before check-in time. Everyone showed us great courtesy & made us feel secure. The location could not have been better, for dining, dancing & gallery hopping. The day & evening concierges were so helpful, it really made our trip memorable. We will most certainly visit here again.
The Mark Twain Hotel never pretends to be other than it is. It is a hotel built long before Big Macs and Starbucks. The windows open (no air conditioning) and you get a nice breeze. Newly updated (paint, carpet, etc.) the rooms are scrupulously clean! If you want a little more space, choose one of the larger rooms. Yes, there is street noise in some of the rooms, but you are in a city, after all.
The staff was helpful and breakfast items were plentiful (I grabbed a coffee, banana, and yogurt). Food in the immediate neighborhood was good. There is a cafe next door that had a line down the street during the breakfast rush (got breakfast later, around 11:30, and it was quick, and excellent.
There is a taxi stand across the street, and transit is close. I didn't rent a car as it is expensive to house them, and you don't really need one in the city (parking in S.F. can be a challenge.)
