The place of Carolina is very nice and we had a great time. It is well located and even if we didn't meet Carolina the communication was easy and fast and her assistant was present.
Carolina really cares about her hosts. The area is secure, nice and close to the center.
The appartement has no window, yes, but this is the architecture of these old buildings and doesn't influence the quality of the place, on the contrary: you'll feel like a local :-). I really recommend Carolina's place!
