Shawn's apartment is just amazing! Me and my husband felt at home there. The bed is not so big (more like queen size i guess) but it is soooo cozy like a nest and it was really hard to make ourselves get out of it in the morning ^_^ Worth mentioning, that shower is spacious and beautifully decorated :)
Just across the street you will find a small shop, where you can buy cheese and wine and grab some quick food if needed. But one should know that there's no microwave in the apartment (though we didn't need it at all). Cozy brasseries are nearby. Tuilrie garden and Luvre are at 5 min distance. Musee d'Orsay is right across the river. Pompidou Centre and Picasso museum are few metro stations away or half an hour walk. The closest metro station is just around the corner! Shawn is very nice. And getting to his apartment is easy and safe. We would definitely recommend staying there.
