Michelangelo and his wife were very nice hosts.
We agreed about our time of arrival and they were punctually there when we arrived.
They explained us everything about the appartment, where we found all necesary facilities, even some nice "extras" as bycicles, huts for the sun, umbrellas..
They also explained where to eat (with some excellent recomendations, as the restaurant Osteria Ballaró) and what to see in Palermo.
The appartment was clean and confortable and according to the description in Internet. Also the parking inside the house was very convenient.
The only "but" was that, if you leave the windows open in the night, you can hear rather loud noises from the street, so the second night we connected the air condition (important!!: the general switch for the air condition is a common electrical switch near the oven!) and closed the bedroom windows, so we could sleep "almost" without noise.
We would recommend Michelangelo's appartment for staying in Palermo
