I had a great time staying at the Casa Particular of Maricela. When I arrived, there was a problem with my room, so she upgraded me. The grandmother makes a really good breakfast, and with the heat of the day, you will not even feel like eating lunch afterwards. The house is in a very nice neighbourhood with lots of Colonial houses. There is a nice wi-fi park nearby, as well as a bank with an ATM (Cajero Automatico) and a nice pub called El Rincon Espanol. In Havana, make sure you eat at the Biky restaurant upstairs (they have live piano and paella with lobster for $12) and go the the Parisien Cabaret at the National Hotel.
