Giovanna's apartment was one of the nicest we have ever stayed in. It looks recently renovated (even better than the pictures), it's clean, the bed is super comfortable, the kitchen is well equipped and they provided some extras like coffee machine, drinks and a variety of breakfast delicatessen. The apartment is less than 10min walk from the main city square and there are a few mini markets close by. The neighborhood might look a bit unsafe because of the narrow dark streets, but that was a false first impression since everything went down really smoothly on our 4 nights there.
Giovanna and her husband were very friendly and they provided good tips on the check-in. My husband and I speak Portuguese and a little Spanish, because of that we understand a bit of Italian. So, even though they don't speak English very well, we understood each other easily.
I would definitely stay there again!
