Le Swann is just an alright hotel. Decent size room compared to most hotel rooms in Europe but small in North America. Shower/bath tub is decent size as well. I like that they provide bath salt as well so you can really enjoy a warm bath after strolling around Paris. Wifi connection in the room was fine.
What I kinda didn't like about my experience here was when I was checking out, I had a bill for breakfast. I didn't know that it wasn't part of my booking. It was kinda misleading info when I checked in. Typically when breakfast is extra charge, hotel staff would inform you that it is for a fee. And, if its part of your room package, they would tell you where they serve it... other than that, it was okay.
I stayed here for few nights since it is a short walk (about 10-15mins.) to Gare Saint-Lazare station. This is like a central station for metro, Euro train, bus...So, this is where you want to be especially when you plan to do some day tours outside Paris. The Metro is in the mall so that's a plus. The Haussman Grands Magasins, La Fayette is walkable as well.
There's also a Kabob, burger joint next to it..
Area seemed safe (although, there were lots of homeless people around next to the station/mall area). I walked by myself at night with no problem.
On other note, I think the area is somehow musically inclined neighborhood since I saw few music stores that sell musical instruments...
Would I recommend this hotel? Uhm, I'm not sure...Location is good, room is decent, bathroom is alright, breakfast was alright (but this is extra charge), staff was so-so... To be honest, I'm torn....If you want to be in the Central public transport accessible location, I would stay here. Although not the greatest, it isn't the worst either. But, if you don't need to be close to the station, maybe book somewhere else.
This is a late post. I stayed on Dec. 2016 less
