BIG! The apartment would’ve fit 6 people easily. Very spacious living room and 3 cosy bedrooms. The only downside is the hot water for showering is kinda unstable as is the case with a lot of other apartments in Paris.
The location is great, close to notre dame, luxembourg garden, pantheon, and a few different metro stops, and many different groceries and restaurants.
Would definitely love to stay here again when we come to Paris.
