Cheap Cuban hotel chain Islazul breaks out of its Soviet-themed concrete-block obsession and goes semi-colonial in this venerable beauty on Plaza de Marte. It has positive staff and 17 clean, uninspiring but high-ceilinged rooms featuring narrow singles. It's quirky in novel ways – don't be surprised if a Chinese salesperson is selling clothes out of suitcases in the hall.
The pleasant street-side restaurant is volumes better than the rooftop disco – if you're trying to sleep at 1am, that is.
