This is a beautiful flat in a location with great transport links. Steph is really nice and speaks perfect English -- made us feel very welcome in his home. We were free to use the kitchen and living room as much as we wanted as he was out working etc. a lot of the time. The building has a lift (which was great because we're used to having to climb a lot of stairs any time we stay in Paris!) and good security etc. We had a small issue with checking in, which was partially our fault as we needed to check in quite late in the evening but it didn't effect the mood or the rest of the trip.
We would recommend Steph's place without hesitation.
