Thanks for the responses so far.
For clarification, when we travel we love to see the 'real' country and get a good dose of culture but tend to prefer to retire to something a little upmarket and boutiquey, so yes, very much want to experience the cuba libra but would like a nice hotel to go back to. Ideally somewhere with beach or a good pool complex and a nice bar for the end of the evening.
I'd greatly appreciate any hotel suggestions. I had a look at vuittonsofstyle's suggestions and the Hotel Saratoga rocks my boat, from their website at any rate. Would also welcome any comments from those who have stayed there?
