Once you accept that this is a boutique hotel in an old building run by the government in a communist state the Florida is excellent. Nothing should surprise, but we found it very well positioned in the centre of the unrestored part of Old Havana, in a beautiful old building,spacious and moderately clean, with effective and quiet air conditioning in our rooms ( but not most of the public areas) comfortable beds, and an efficient staff.
It was certainly quiet while we were there, although it was the low season, and you really felt it could be your own home! Our two rooms were on the top floor which in the old house would have been the family's bedroom floor. On that floor rooms went off a wide internal balcony furnished with comfortable settees. The whole place was so quiet and elegant that the part of the continuous balcony outside the rooms was like your own personal lounge area. We were told the floor below which had a much narrower internal balcony would have been the servants' quarters in the original house. I'm not sure how spacious those rooms would have been!
There is a travel desk in the hotel run very efficiently by a staff member from a local tourist company. She arranged two personal tours for our party of three with a wonderful English speaking guide. We found that a great plus in a country where English is not widely spoken. There is a money exchange virtually across the street, again a great bonus.
Stay here and you are in for a great experience.

The staff here are friendly and do their best for you. The room we stopped in was very dark, even with all the lights on. My daughter stopped in the room with us on the sofa bed, which was very uncomfortable and didnt seem to fold out properly.

On arrriving our room was swimming with water from the air con. not what you need when arriving after midnight! the staff quickly mopped this up, but in the 4 days we stopped and the twice that the man with a spanner looked at it, it leaked to varying degrees during the stay.

the food was OK, but having stopped at another nicer hotel in Cuba before arriving here I think we had previously been spoilt.

The shutters to the street do not have glass in them, in itself not a problem, but the street was very noisy, especially from barking dogs, which could keep you awake.

On the positive side, stopping in the middle of Havana is an experience, and the hotel has an elegant style about it. The people are friendly and you get a real feel of what Havana is about. There were several restaurants and bars playing real Cuban music nearby and the atmosphere was good. It is just unfortunate that some things are difficult for the Cubans to get hold of, this probably including parts for air conditioning units.
