This is a great place to stay! We had a conference next door at the Palacongressi Oltremare and it couldn't have been easier. Plenty of space, fully functional kitchen, and great location--it's also right next to the train station (15 min Metro ride to the city center), a grocery store is nearby, as are restaurants, coffee, and a tiny convenience store. It was good to have a washing machine while there.
Annarita was wonderful and gave us lots of tips and even ordered delivery pizza for us on the phone on the first night after a very long journey. She also offered easy pick up and drop off at the airport.
Very happy with our choice to stay at this flat.
