Gabriele is a fantastic host and very helpful. The photos and description of the apartment fully reflect reality. The rooms are very big and it's got 2 nice bathrooms. We were 6 people and this was perfect.
The area of San Lorenzo is very nice, lots of young people and therefore lots of bars and restaurants. It is not very touristy, therefore perfect if you look for an area that is typical and off the beating tracks. Plus it is just next to the main train station. It would definitely stay there again...
