Claudia accommodated us really last minute at her lovely apartment in Graça. The apartment was easy to find, it was very comfortable inside and we loved how she decorated the place. We seriously wished we stayed longer in Lisbon, partly due to this place and the neighborhood. We never actually got to meet Claudia, but communication with her was excellent, the apartment was spotlessly clean, the bed was comfortable, wifi worked great, the kitchen was very well stocked (though we didn't really use it except for coffee/tea) with pots/pans and a variety of spices. I've bookmarked her place in my favorites so I know where to stay the next time I'm in Lisbon - a place I HIGHLY recommend to friends, family, and everyone else.
Quick note: My boyfriend and I had a rental car for when we drove down to the Algarve coast. We drove it into the narrow, steep streets of Lisbon right up to Claudia's apartment, and found parking in the neighborhood right away. We left the car where it was parked and just walked around/took public transportation within the city.
Say Ola bom dia! to the neighbors - everyone is very nice and friendly.
