Fabio replied to all my messages within minutes -- or literally immediately! When we arrived, his son was waiting for us outside the building, which was extremely kind of him especially as we were a little late. As the father, also the son was very nice and polite and spoke good english. This is most probably the cleanest little apartment we have booked thorough Airbnb. As for the location, very close to the apartment is the CityLife shopping/residential district, with apartment blocks designed by 'star-architects' as Daniel Liebeskind and Zaha Hadid. (Though we went to CityLife first because of a food store that was open late in the evening.) Also one original reason we booked with Fabio is that the metro station is near, making it easy to get around. Thank you Fabio!
