Stephane is and excellent host. He answered all our email questions promptly, so that we knew exactly what to expect when we arrived in Paris. The flat is only a short metro ride from Gare du Nord, which was excellent since we arrived on Eurostar. The metro station is literally 1 minute from the flat so even with two suitcases and a child we managed without problems. The flat itself is lovely, safe, quiet, clean and spacious, with everything you could possibly need for your stay, including free WiFi. The location was absolutely perfect for us as we were able to walk to most sights (including the Eiffel Tower) and if we couldn't walk somewhere, the metro connections were really good. There is a lot of nice restaurants around, but also plenty of 'take-away' shops if you fancy a quick meal. There are supermarkets just round the corner, one of them has a good size bakery at the ground floor, which meant fresh bread for breakfast every morning. Mmmmm.
We found that, whilst many Parisians don't speak English, if you make an effort to talk to them in French, they will make an effort to understand and help you. (Google translator came in very handy at times). :-)
We thoroughly enjoyed our stay in the flat, felt a lot more comfortable than we would have done in a hotel and will be very happy to stay there on our next trip to Paris, whenever that may be.
A big thank you to Stephane for being such a great host.
