We stayed at Costanza's apartment for 3 nights and were happy with our stay. The location is perfect - we walked to all the big sites or took buses, which stop just around the corner. The apartment is small like it looks in the pictures but for 2 people for a short stay we didn't mind. Costanza was super nice and very responsive if anything came up. I agree with the other reviewer who said the air conditioner wasn't very good. It was hot when we were there as well. But other than that we had a perfect stay.
