The description of Simeng’s flat is very accurate — we had a great time staying in this area, right next to the Sorbonne and Luxembourg gardens, where you can grab some snacks and spend the day. The water was always hot for the shower, and we loved the kettle for tea.
For adults visiting, be aware that the second bedroom’s bed is very small — but my partner and I had a great time in the larger room (where the piano and dining table is). Overall, great stay, easy check-in, and really cozy apartment that isn’t professionally managed, just nice and homey.
