Recently my sister got engaged , we have booked sonotel hotels for 2 days . Sonotel hotel services is so worst , we have to call twice and thrice for house keeping and room service and afterward they will come. One big problem is electricity. Sonotel is rated 3 star but it couldnt provide 24 hour electricity. hotels rooms are so conjusted and there is no fan on rooms , only ac is there. In the season of monsoon no one can live 24 hours in ac . I will prefer you guys if your staying in dhanbad please stay at other hotel like 17° , skylark etc
