Maria' apartment is really cozy and nice. It locates near the boarder of the ZTL and you could take a tram with 1.5 euros into the city center. Maria's is very nice and answer my questions about the plug and parking lot with patience. Small hints for parking: you could find some parking marked in blue in the opposite of the apartment and it costs 1 euro an per hour during 8 to 20 o'clock.
