We had a great time at Catherine's place - which was in the perfect location to explore Paris! Easily walkable to hot spots and right next to the metro if you prefer that. The flat is spacious yet cozy and comfortable, although it is a bit dark (as it faces another building) and can be a bit loud at night (due to the central location). Would highly recommend going to a local bakery (we really enjoyed 'Stohrer' and 'The French Bastards' nearby) and bringing back pastries to enjoy for breakfast in the lovely dining room. Thanks again to Catherine, who was incredibly responsive and friendly throughout :)
