The lady welcoming us at the appartment only speaks Italian, so the communication was a bit difficult in the beginning. She was very nice though and despite the language barier she could tell us the most important things.
The location is in the red light district, but this sounds worse than it is: there are some guys and ladies on the street, but they didn't bother us and there was absolutely no feeling of unsafety. If you walk down the street you are already in the city centre with the nice restaurants and cafés, which was nice.
We, 2 couples, really enjoyed our stay in this appartment.
