Sound is a major issue at the Hotel Shine: people shouting all night in the square, bins being emptied. It's a great location, but bring your earplugs.
Aside from the lack of soundproofing, you might notice the absence of some useful hotel items like a rubbish bin, drinking glasses or soap. They kept putting the clean towels on the toilet lid!
Wifi didn't work to start with and we had lots of interaction with staff, who were excellent: very helpful and friendly. When it finally got going they told us it would only work as far as the third floor!
It's an ok hotel, but for EUR80 a night in Grenada, you can do better.
