Dario was very helpful right from the first time we spoke. He provided information prior to our arrival and was at the apartment to greet us. He left water and two sodas in the fridge, which was very kind.
The apartment is in a perfect location. You're close to metro stops, the main train station, a great grocery store, many attractions, and the port. There is also a ton of information available in the apartment to help plan your trip. We used it to help us plan where all we were going to go and the available map was great for navigating the city.
I highly recommend Dario's flat as your home away from home, not only because of its location but also because of Dario's hospitality.
