Barbara is a very good host, she is fast in her replies and immediately helpful when needed, otherwise very discrete. We only met once, she was kind and practical - she even asked her mom to bring something that was missing in the apartment. Thanks again to both!
One thing that for us was a little unusual about the apartment is that in the bedrooms there is hardly any natural light, the small opal glass windows open on internal courtyards, basically you can't quite tell if it is day or night and have to keep the light on also in the morning. Also, since the apartment is far from soundproof, you can hear people walking up the staris or even neighbours snooring next door...
Other than these two things - the apartment is very clean, the living room is bright and spacious, and the bathrooms and kitchen are absolutely fine. There were more than enough towels and extra sheets and pillows.
