The studio is good for a short stay but I would not recommend staying there longterm. I stayed for a month and wouldn't do it again. A few times it was very loud because of the other guests. The hosts apologized but I didn't sleep for a few nights because of that. The apartment which I would describe as big hotel room and not as a apartment let pass any noise. Probably also because the entire building is built how it is built.
You don't communicate with the host Mariano during your stay but whit his staff, sometimes they responded quickly, sometimes I had to wait very long. The location is okay, like any location in Palermo Soho or Hollywood.
