Liu’s apartment is an easy walk to Notre Dame, tons of restaurants, and Metro and RER lines. (Note that the Saint Michel stop on the RER C is closed for renovations until December 19, 2022 so you’ll need an alternate route to the Eiffel Tower or Versailles.) Liu was also extremely communicative and accommodating throughout the process, but especially at check-in when we arrived later than originally planned.
The main bedroom and en suite bath was quite roomy but my brother and sister-in-law found the loft bed in the second bedroom uncomfortable and thought the ladder was challenging to navigate, especially in dark in the middle of the night. On the plus side, both showers had great water pressure, the wifi was extremely fast, and the double-paned windows blocked out the considerable noise from the busy and popular street below.
We had a great stay overall and would definitely book again for future trips to Paris!
