We really enjoyed our stay at Casa Alina. She is a friendly host and a good cook! The house is clean, comfortable and well located in Habana Vieja, with a lovely view of the Capitolio from the kitchen. The room had 2 double beds, air conditioning and a useful fridge with bottles of water (at 1.50 CUC each). The bathroom was across the hall from the bedroom, but we seemed to be the only ones using it.
Alina speaks a little English and with our basic Spanish we got by just fine. She was really great at recommending (and helping to book) other casas for our trip, which was very much appreciated.
Overall, we would recommend staying at Casa Alina!
