The place is perfectly located. The apartment is very clean and you'll find everything you need. Franscesca is an extremely helpful & kind host. She arranged an airport transfer for us. (It costed us 45 EUR which is a good price if you keep in mind that a taxi will charge you 60 to do the same trip at night)
Upon our arrival, she took the time to tell us about the neighbourhood & answered all our questions.

There is some street noise, but that seems just normal in such a big city + after a day of exploring you will be tired, so you won't have the time to bother about it.
The 2 double beds are very comfortable. The sofa-bed on the other hand, isn't as comfy to sleep on. A perfect place for 4 people.

The last day, we were allowed to leave our luggage in the apartment for later pickup.

Would definitely stay here again!
