This flat is massive by any standards, and particularly Parisian. Easy ground-floor access through a large, well-kept courtyard with very few steps to navigate, which is always helpful when toting luggage. Very comfortable beds and bedding. While many hosts are "generous" in their descriptions of the walk to public transportation, five minutes is completely accurate, and the route to the Gambetta station is a straight shot from the flat. The neighborhood offers numerous nice grocery, patisserie, boulangerie, fromagerie, dining, etc. options. Our driver from Gard du Nord asked why we were staying so far out in an area where there was "nothing to see," but we found that line of thinking to be erroneous as it was quite nice to be away from the crush of tourists in Paris city-center and a very short walk from Paris' largest and most interesting cemeterie, Pere Lachaise. (We highly recommend Rick Steves' audio walking tour of Pere Lachaise for an enjoyable few hours of "real" Paris that will clearly direct your route to the graves of Chopin, Moliere, Oscar Wilde, Gertrude Stein and Jim Morrison, among others.)
The bathroom set up in a bit unusual, but it wasn't an issue for us. One large bath near the bedrooms has a lovely shower, double sink and the washer (no toilet). A second full bath includes a smaller shower, small sink and toilet behind a pocket door, with the second toilet and third bathroom sink for the flat right next to that small full bath. Because both toilets can be utilized privately with separate doors, this isn't an issue; simply note that they are on the opposite side of the flat from the bedrooms. Again, it wasn't an issue for us, and we had the maximum eight guests sharing the flat.
A folder of information regarding the appliances, neighborhood, etc. would have been helpful, but we made do without.
The building is probably almost always quiet, although we hit a national holiday (Ascension Day) and a crazy loud, late party in the flat next door that shares a wall with two of the bedrooms. While unfortunate for us, that was likely an unusual situation and isn't reflected in our rating as we would recommend this flat and the neighborhood to anyone.
