I would say Holiday Village and Sunshine are in great positions at the end of Candolim Beach Road, and surrounded by nightlife, but are basic, and you need to pay for the upgraded rooms. Both have small pools, in the shade, but are close to the beach. The Hideaway is further from the action and beach, but is a much nicer hotel, so more expensive. Again a small pool, in the shade. Next door to the Hideaway is the new Silver Sands Serenity, which is the nicest of the four, and has a rooftop pool with great views. This is the most expensive of the lot.
So it depends on your budget and priorities which you pick. Cheap but well positioned or upmarket but a bit of a stroll to beach or nightlife.
