Ubaldo's place is very nice. It is big, secure, has a fully stocked kitchen, great wifi connection, and is a 5 minute walk from the super market. There are a few different buses that stop across the street for easy access to the city.
Ubaldo is a very nice guy, and he picked me up from the train station on time for 10 Euros, and then returned me there for free when it was time to leave.
I can't think of what would have made my stay any better...it was great.
