1--First of all we strongly recommend
you NOT to stay in a "casa particular"
that is not legally authorized for being rented to foreign tourists,
this can be a big problem for the owner of the place and for the tourist
2--We think that is a very good idea to
make in advance reservation because the lodging in cuba is sometimes
hard to find , so.. taking into consideration that most of international
flights comes late at night and with the tourism booming is sometimes
difficult to find nice accommodations in havana.
