Me and my boyfriend stayed at Andrea's house for 3 nights.
It's 10 minites by walk to the city centre and a couple of minutes by walk to the metro station "Materdei" .
To get to the actual house , you have to walk trough his aparment's kitchen but it wasn't a big deal , the apartment was nice, cozy and clean. You also have access to a garden an a terrace wich could be really nice in summer. Would definitely stay here again, and reccomend it 100 %.
