We loved this apartment. It was warm, quiet, spacious, flooded with light, oozing charm, and extremely good value. The wifi was strong, and there were plenty of power points. We loved cooking in kitchen with its view out over the rooftops of Paris. There are several very good little supermarkets with a few hundred metre radius. Plus oodles of good bakeries, cheese chops, etc., in the neighbourhood.
This is my favourite part of Paris to stay. It is not too touristy, is surrounded by amazing food, is close to good transport options, and is walking distance to most major sites. For an authentic and reasonably -priced neighbourhood eating experience, try the little bistro around the corner on Rue Montmartre, next to the Catholic Church. It has amazing heritage tiled murals on the wall and the tables are so close you may find yourself conversing with your fellow-diners.
We arrived by train Gare du Nord station. From there it is one stop on the RER line B to Les Halles metro station, which has escalators all the way to street level. (RER line B also services both major airports.) From Les Halles it is a very short walk to the apartment.
Communications were excellent, entry instructions very clear, and Ines checked in with us during the stay.
You do need to be mobile to access the apartment. As described in the listing, there is a (tiny) lift most of the way (a luxury in Paris) and the last floor is accessed by two flights of stairs. The final stairs are extremely narrow and steep - we are reasonably fit but found it challenging to get our average-sized suitcases up the last bit and into the door. For us it was well worth it to get to such an amazing space, but it is something to be aware of if have mobility issues or a lot of luggage.
Overall, an amazing experience, and we would definitely try to stay here again if we return to Paris.
