Good Hotel at Good Price
Chancellor Hotel is located almost in front at the Union Square of San Francisco. The location is unbelievably nice and really pratical! It is in Powell Street, where you wiil be able to catch the Cable Car (stop just in front of the hotel) or walk towards the Chinese district located not so far from it.
For the period when I went, it was the cheapest in that area, no way to reach that rate for the hotel in the surroundings.
Breakfast is in the average, cleaness as well. 
The room is not very big, let's say quite enough for a 1 person stay. Bathroom a bit small but you got everything inside.
In conclusion Chancellor Hotel is really fine, nice, confortable and with a VERY good location and price (for business). 
The only very bad thing to be highlighted is that its value is stained by a mediocre and very poor kindness, hospitality and professionalism from the people who are working there, reception workers first. This is a very important point on which to work to make this Hotel a very high rated and competitive solution overall!
