We had a great stay in Paris staying in DD’s place. The location was even better than I expected on a quiet (but not deserted) well-lit street not far from anything you would need (metro station, attractions, restaurants, etc.). Dd was very friendly, helpful, and quick to respond. We were able to work out an early check-in to accommodate our arrival time, which was great, but Dd also offered to hold our bags in the event the place was t ready in time.
The size was fine for myself and my 7 year old son (the loft bed was a big hit for him), however I wouldn’t recommend the space for any more than 2 people.
My only complaint would be the dampness and mustiness that are mentioned in other reviews.
