Will be in Kolkata for about a week and am trying to decide which hotels best fit my budget and needs. I am considering the Lytton, Astoria, and Fairlawn. Will be travelling with a friend. We intend to do some volunteer work and will need to meet with some friends. Is this place close to the Indian Coffee House? Also, if the rate is for a double, does that mean the cost of the room or per person?
