Carolina and Christina's place is really great. The whole place had for us "Bologna's look" so you have an experience just being there. Apartment itself is really great, it has all you need. Location is perfect, you are 10 minutes of walk from the main city center (the whole city looks like a center because of beautiful streets which are around you). Carolina responded really quickly everytime I asked something.
I really do recommend this place! We had an excelent experience here.
