Cristina's place was really well placed. She herself is friendly and helpful. We had a slight issue with the electricity the first day we were there, but she helped us sort it as much as she could and her husband came over on the second day to check everything was fine.
There was a bit of confusion regarding the lack of door for the downstairs bedroom, and the fact that the toilet had no lock, these however didn't really impact our stay much.
Overall a good place for a very good price.
