Stays like with Roberto are the reason I'll always choose Airbnb over any hotel. Great personal touch and hospitality.
The apartment is cool as well, some things that were not clear from the pictures: own bathroom, there's no kitchen but you have a small fridge to keep some food at home and the basics for eating or putting together a sandwhich. And the coolest: you have your own rooftop! We didn't really use it in the winter but in the summer I'm sure it's amazing! Also the hospitality Roberto and his wife provides is perfect, they'll suggest good local places, attractions and local specialities, everything you need. Great location and area, good connection to the airport and the train station as well.
