Five-stars. There are two identical buildings for this hotel - one is the Adele, the other is the Jules. No difference between the two & are next door. The hotel is down a pedestrian-only walkway and is close to two different metro stops. Easy walks. The hotel has an elevator or spiral staircase. Rooms are small, but think "boutique hotel" and it'll be what you expect. AC is available, and it lets you set the temp to as low as 66F. There is a safe for valuables. The TV is exclusively French. There is no bar soap, but quality body wash, shampoo, & conditioner. The lobby is small, but very comfortable. They offer a breakfast (which we did not opt for) that looked like a variety of meats, cheeses, bread, eggs, and bacon. They do, however, offer coffee and tea all day long and a free "teatime" in the afternoon with some pastries. There is purified water available in your room (refilled daily) and in the lobby too.
English speaking staff, very willing help. Had a box of European electrical converters in case you forgot yours. Room was refreshed daily.
If you're not familiar with Paris, it's hard to figure out what is the best, safest, etc., area. This hotel hit all the marks. Close to two different metro lines. Uber from Eiffel Tower was $30 & Welcome Pickups from CDG was $125, both times for a five-person van. Good dining options within a couple blocks, boulangeries, & a small grocery store too. Overall, great visit. Great option for first timers & return travelers.
