The Sunflower is what all budget hotels in Kolkata should strive to be. It's housed in a grand 1865 residential building – take the vintage lift to the top then climb one floor to check in. Rooms can be slightly spartan but they’re assiduously cleaned, with high ceilings. Pleasant communal spaces are available, and the rooftop garden at dusk is delightful.
A few triple rooms (with/without air-con ₹2250/1950) are also available. Discounts for long stays if you let staff know in advance.
