We booked the Miami guest house but actually stayed in the Tamiami which is opposite in the same road. Luis from the Miami guest House met us at the car rental centre Miami airport and next day very kindly took us to the Porti for our cruise. . We did see one of the units and it was very nice. Just a short distance away is a good supermarket and several restaurants. If you are prepared to use public transport (which is quite good in Miami) you might not need a car while staying here. Although we did not stay here I would highly recommend both the Miami and Tamiami Guest House. .
