The apartment is located on the 4th floor of a modern building with secure entry. There is a lift available that was very convenient. The apartment, itself, is fairly small, but was just fine for my wife and myself as we used it as our base for Paris sightseeing. We were worried about the bed, since it lowers from above and both of us are 6' or taller. However, the bed was very sturdy and suprised us with how comfortable it was. The apartment had everything we needed for a nice stay, including a full size refrigerator, coffee maker, washer/dryer, etc. We could not get the dryer to work, but it wasn't a huge deal and in fairness we did not reach out to find out what we were doing wrong.
The best thing about this apartment is the location to the Paris Metro station. It is literally just a couple of minutes to get on a train. The area seemed safe and we did not have any concerns during our walks through the neighborhood. You are also close enough that you could walk to the Eiffel Tower in less than 30 minutes.
We enjoyed our stay and would have no problem staying herea gain if we ever find ourselves in Paris in the future.
