Sleepy little town with cheap booze. Full stop. Don't expect any thing else. If you are travelling with a group might be a good place to visit coz of cheap booze but a big no for solo / family.
Arabian sea touches some of the hotels. They have nice beaches but the sand is black and one can not sit n them.
Was a part of the erstwhile Goa, Diu and Daman territory and hence some parts look like Goa. A nice place to relax.
Daman is not a city for sightseeing since the beaches which are the only tourist attraction are dirty.
