Rosa's place was great and worked out very well for us! I booked it last minute the day before and she was quick to respond to my inquiry and even let us check in a couple of hours early.
The location could not be faulted! It was very centrally located and you could find anything you might need just within walking distance. The place was clean and the beds were great. The bathrooms were newly remodeled and though the boiler was on the small side, the hot water was quick to come on. I would recommend quicker showers in the winter since the hot water gets used up sooner having to warm up much colder water. The towel warmer was a nice touch as well! There is a cooking smell from the restaurant Pesce Fritti downstairs that tends to waft into the kitchen area, but there is a door that separates the kitchen from the rest of the apartment, we just kept this close and it was not an issue. It was also nice to have a microwave and washer in the apartment. Having an elevator also came very handy as the apartment was on the 2nd floor (that's the 3rd floor for Americans) especially if you have heavy luggage.
I would not hesitate staying here again! Grazie Mille Rosa!
