Would definitely consider again for the convenient location, affordable price, cleanliness and size of the space. Although the window is just over a little street, it's not noisy at all, you can only hear when the town starts to comento life in the morning, but even those sounds can be reduced with the thick wooden blinds shut.
Only downsides for me were that the bathroom was getting quite warm while opening the bathroom windows was bringing some cooking smell from an interior space downstairs and there was some smell by the front entrance doors leading to the stairs. But that is only for few seconds until walking through the property locked doors on first floor, it would not keep me from returning.
Good location, within the old town atmosphere, 5 minutes walk to the 101 bus station taking you to the nicest beach in Palermo and 5 minutes walk in the other direction to find the busier part of the old town.
Don't expect the nicest entrance to the accommodation but once inside, room was spacious, memory foam mat and pillows, balcony over the street and really big bathroom that never bothered us for being on the hallway, as it was private.
Common dining space was not something that we needed but looked nice and clean, with use of a fridge with allocated shelving for each room.
Some affordable family owned places for breakfast or fast food located just downstairs that we tried during our short stay were really worth out time. There is option just around the corner for wider menu with table service.
Clearly a property to consider no matter what you plan to do in Palermo.
Before I forget, communication for self Check-in was really clear and smooth, one doesn't have to stress about that, specially convenient for late evening arrivals.
