Dan's apartment was absolutely amazing! The apartment is inviting, bright, clean, spacious, and comfortable. It is remodeled and has great amenities but retains an incredible Parisian charm. It was only a block from the Bonne Nouvelle metro stop, which we used most days to get around. On our first day, we decided to walk to the Louvre and encountered some very quaint streets on the way. We also enjoyed the Frenchie Wine Bar, which was only about a 5-10 minute walk away and one of the best meals we had during our trip.
As for Dan, he was a great host, he quickly responded to our questions, was flexible, and met with my parents when they arrived!
There were 6 of us and we all were very comfortable and grateful for the 2.5 bathrooms in the apartment. My husband and I took the room facing the street, while the other two were facing the courtyard. It was a relatively quiet street, but at night there was some noise from people walking by after a night of having fun at the bars. My husband and I typically travel with earplugs (and use them in our apartment in Boston) so we had no problem at night. If you are a light sleeper just be sure to plan accordingly if you are going to stay in the room facing the street.
I definitely left Paris wishing that we could've had a little more time each day to just enjoy relaxing around Dan's apartment. This was a great place and I highly recommend it!
