I am a graduate student and I lived in Rui's apartment for two months while doing research at the BNP and ANTT. The location is great: a nice walk to the campus, a block from the Roma metro on the green line, a block from the Roma-Areero train station, and lots of small restaurants and cafés. There's also a grocery store on the street and a bike path that runs behind the apartment. I had a friend visit me and the apartment was a perfect base for exploring the city by metro. The apartment itself was comfortable and spacious for one person. Rui was a very kind and capable host: when my flight was delayed almost to midnight, he came and picked me up at the airport; he always responded quickly whenever I had a question or a problem; and when there was a minor plumbing issue with the shower drain he arranged to have it fixed quickly and efficiently. All in all I had a wonderful stay.
