Gabriella was the nicest host ever. I didn't meet her but we communicated by mail and she was very quick to answer. She was very helpful and recommended many restaurants.

As for the flat, it's 15mn from the train station by foot. Considering that there is only two metro line, it's not bad at all. We were able to walk pretty much everywhere.
The flat is nicely decorated. The bedroom is a bit noisy at night but unless you are a very light sleeper, it should be a problem.

I recommend this apartment without hesitation!
