Maria Luisa was a great host. The communication was spot on and she even met us at the train station and walked us to the apartment. She allowed early check in as well as late check out. This really helped seeing as we were unsure of our departure time due to an appt at the consulate.
The location of this apartment was nice, perfect if you need to go to the American consulate. There are also some good restaurants/bars near. You can do the lungomare walk. It is also easy to walk to the Spanish Quarter, we walked everywhere.
The studio is tiny, but comfortable and has everything you need for a short stay. The studio is on the 3rd floor but there are 9 small staircases to reach it so it is a bit of a workout so keep this in mind. (We knew there wasn't an elevator) The studio was mostly well cleaned and we would recommend it as it's a good value.
