Nathalie's place was pretty fantastic. Its a spacious apartment. We initially were planning to have 3 guests, but ended up with 2 guests, but three people could easily sleep there (she has a bed and an extra queen size mattress that can be placed next to the bed on the floor). The place is close to a couple of metro stations (~3 minutes walk) and there are plenty of stores and restaurants around for food and anything else. All the necessities are fully provided for, as well as extras like hand towels and paper towels, which was nice. Would definitely recommend it to anyone thinking of staying in Paris.
