Our stay at Casa Sara was fantastic. Sara and her husband were very welcoming, friendly, and helpful.
The location (right on the Malecon with ocean views!) was perfect. Close to La Rampa and within walking distance of Old Havana. We got our own bathroom and mini fridge in the bedroom with use of the kitchen and living room facilities. If you want, Sara makes a delicious and plentiful breakfast at a small extra cost (definately cheaper than you could get at a restaurant!)
I would stay here again in a heartbeat and highly recommend this casa particular.
