Marianna's place is in a great location. The apartment was clean, the beds were comfy - there was a kitchen table to hang at and a couch to chill out on. There are two air conditioning units - one in the bedroom and one in the main room. We loved having two different "climates" :) . Marianna's place is not soundproof, though I doubt any other place in Palermo is either. Take some ear plugs to drown out the street noise. A few minor things that needed improvement in the apartment which have been suggested to the host. Great place. Would recommend.
Make sure you check out the neighbourhood. Head to Piazza Rivoluzione for aperitivo. Wander down the street to local shops and TONS of bars along the way to Via Vittorio Emanuele and eventually the street food market in the p.m. at Vucciria Market. All this within a 10 minute walk.
