We (a family with 2 children) spent 5 great days in Piero Giuseppe`s place. Really close to city center (10-15 min walk) and really accessible to public transport.
The apartment is clean, safe, with kitchen amenities (if you have to feed warm food to little kids), maybe a little chilly in windy days (but we used the AC to warm up the space).
Piero Giuseppe gave us great recommendation: to visit, besides others, university`s anatomy and anthropology museum (inspirational scholastic environment for kids), and to use rather taxi than public transport from and to the airport for less costs.
