Alix's flat was beautiful and in a perfect location to tour the city. The area (Bastille) feels quite safe and is very lively at night, during the whole week. There is more than one metro stop within a five minute walking distance, so getting around isn't a problem. & Alix is a fantastic host: she's easy to get a hold of, should you ever need anything.
I would certainly stay here again if I came back to Paris.
