Our stay with Louis was very good. We had some issues checking in and with a few issues at newly renovated flat but we enjoyed it anyway.
Cons: The sleeping loft is very tight and the stairs leading up to it need some work as they felt a little unsteady. The place was so new that it still smelled of paint and was a little cold and unwelcoming. The stairway to get to the apartment was also unlit so it felt sketchy getting there.
Pros: LOCATION! The flat is near everything. Its a 10 minute walk to so many different sightseeing destinations like the Louvre or the Jarden de Tuileries. There are world class desserts and bakeries literally across the street as well as a market for all your basic needs. There are tons of restaurants and bars nearby as well. There are 2 subway stations and a bus stop within a 5 minute walk so getting to other parts of the city are easy as well.
We had a wonderful time in Paris and Louis' flat had a big impact on that. Thank you!
