This was our first trip to Paris, and my wife picked out this gem to stay at.
The room had a lot of things going for it, including dark shades (if you're out on the town until the wee hours of the morning and want to sleep in, you'll appreciate this), a very comfortable bed, adequate air conditioning, a safe neighborhood and absolutely easy transit from the RER or Metro to the hotel - it's 2 blocks maximum.
You DO NOT NEED A RENTAL CAR in Paris - in fact, parking is very hard to come by (as evidenced by the very creative way people parked their vehicles there). If you are reasonably physically fit, you can make it to the Metro or RER stations, and get anywhere you need to go. We were able to hop the RER from the airport and basically get to within 2 blocks of our hotel at the most, and then take the same or other stops to ride the RER or Metro to where ever in Paris we wanted to go, and boy, did we go places in Paris. We were averaging 10 miles of walking a day.
If you are in good shape, you can literally walk to see Notre Dame, the Left and Right Banks of the Seine, and even the Lourve. We walked all over Paris.
The neighborhood is very clean and safe apart from the occasional dog owner who doesn't clean up after their mutt. The hotel has good security - the front door needs your key card to enter, as does your room door. The hotel is within easy walking distance of over 50 restaurants, and I'm probably underestimating that. We didn't eat at the same place twice in our stay.
We were able to sleep during some exciting World Cup 2014 games being shown in the Irish pub downstairs, but we were on the third floor. I think the second floor would be challenging.
The rooms were very quiet - we didn't really hear our neighbors. You'll want to use your shears at least in the rooms - this is a typical narrow Paris street, and you look directly into apartments across the street, and vice versa.
There were two observations that weren't great - the shower (only, no tub) drain ran slow, and the air vent in the bathroom was plugged solid with lint. Otherwise, everything was great.
The double room we had came with a TV (which included some pretty wild French programming with strong sexual themes and frontal nudity- beware if you are prudish!) and a mini fridge. We didn't discover it until later, but there was also a cook top hidden under the counter the mini fridge is under, which included a sink and cook top - you lift the counter up to access it.
All in all, it was a great trip to Paris, and the room and it's "location, location, location" made it all the more better.
The elevator was a trick - it was a three person, standing side by side, otherwise, you're on the spiral staircase - you might as well get used to them, they are in most of the museums and tourist spots.
