(Parks might not matter as we are getting closer to winter).
as far as palermo is concerned, the parks are a HUGE plus (for those who like exercise and open space ), and the parks are very active and attractive year around, not just in summer. palermo is expensive but has great access to the rest of the city. if you live in a barrio where you have to take a lot of buses, that can be a real drag. but it's a matter of cost.
