We travelled through trip advisor prior to our trip to the Grenadines for a hotel on Union. The only option listed was the BigSands - which was closed for a refurb. So instead we contacted a hotel listed in the Hunters guide.

We arrived to find the hotel literally rotting away. The room did have aircon and clean sheets but the bathroom was a partition in the corner(not full floor to ceiling). The bed was a foam mattress about 2 inces thick and the pillow were of the chopped foam variety. I've stayed in some basic places in my time but this is the first time I have had to pull furniture in front of the door to secure myself.
We checked out (payed our 173EC) and moved... quickly!

The bar and restaurant are deserted and there are better options. Stay away and instead you could try
1. The anchorage - we ate there. Grumpy staff but a beautiful setting and we met folks who stayed there and said rooms were good and under 100 US.
2. Or we stayed in the Kings Landing hotel. It was 95US but did have a pool and very nice sea clean sea view rooms. (I'll write a separate review too)

Stayed at the Clifton Hotel Union Island after having travelled blissfully through the Grenadines to this, our final destination. The Clifton was a huge disappointment. Despite being right over the ocean the rooms have no terrace. It was a depressing bare room, with a curtain instead of door to bathroom. The shower which was barely a drip stopped icompletely in mid - shower and though the indicated that they'd up the water pressure it never started again. We stayed here because it was likely the least expensive hotel we could find, and we were flying out the next a.m., and it did fit that bill. We also erred in ordering a beer downstairs and they charge an outrageously high price for a 1/2 size bottle of beer ($8.) I'd look for somewhere more pleasant next time.

Having previously spent time in Bequia and Mayreau we enjoyed Clifton on Union Island. The hotel is convenient to everything in town. The Family operating this property could not be more accomodating. The restaurant is great as well.We opted to spend a couple of nights in the guest apts. at Big Sand Beach. Again, we were not disappointed. This Beach was quiet and beautiful. A small restaurant was excellent nearby and offered all meals! We were very happy at both the Clifton Beach Hotel and their affiliated apartments!
