The good - Location was excellent. We liked being close to the Eiffel Tower and there was good food choices nearby the flat. The water was hot and had good pressure. We liked that it felt like a good neighborhood, with other hotels nearby and it was decently spacious, considering the location.
The bad: the flat was not particularly clean. There were cobwebs in the bedroom, most of the horizontal surfaces had dust on them and the shower and sink had stains. Just walking from the shower to the couch my feet would have things sticking to them. It wasn’t terrible it just seemed like it hadn’t been cleaned thoroughly in some time. Our other issue was the check in. Perhaps it is a French rule but arranging a time to check in in person, just really feels like a needless burden for a traveler. We’re already dealing with train and airline schedules beyond our control and then to have to set an exact time to meet the host just adds to that. I know this is fairly common in Europe and perhaps it is a legal/cultural/etiquette difference from the more common lockboxes used in The USA but we did stay at two other Airbnb’s during our trip that did not require an in person check in and that was much much easier. They were flexible about the time which helped.
In summary, if I was coming back to Paris I would look to explore other air bnb options first but would consider staying here again.
