Our stay with Sylvia was good.

Location:
During our stay the metro system was having a strike and it took us around 30-50mins to get to the Eiffel Tower, and other attractions.
The neighborhood seemed safe to me, but we weren’t out past 10pm.
There was traffic noise at night and constant sirens driving by, although it didn’t bother me, you may want to bring ear plugs if you’re a light sleeper.
Place:
The room is spacious, and the bed very comfortable. The WiFi is fast. You also have your own private balcony. The toilet is shared and it was clean, so is the shower. We didn’t use the kitchen. Although our room was super clean and shower was too. At our time of our stay the apartment had a little box order when you entered it, but not in the room.
Hospitality:
We never actually met Sylvia, we arrived when she was at work, and she left us a key. We bumped into a guy when we arrived. But he didn’t greet us, nor show us around as he was on the phone. From there, we sort of guessed where everything was.
Overall, Sylvia’s place was affordable and was just what we needed; a place to sleep at night after a day of being in the city.
